RE: Gas Engine - Fill It Up

This question is a bit tongue 'n cheek. I've traded my diesel for a gasser. It's been so easy to pull thru truck stops to get fuel. Now what?? Any tips on finding gas in locations that are easy to pull thru while towing a 5th? We refuel before each trip. If I need to refuel while hitched, I have a list of truck stops for the major highways in our state. You should be able to find truck stops on any Interstate freeway with a Google search before the trip.

RE: Max Pressure Cold vs Hot Pressures - How Much Is Too Much

I run 108 PSI cold (usually about 65 degrees in CA) and 120 to 124 PSI warm. Temp increases by about 16 to 20 degrees over ambient. In three decades of DPs, most inflate about 5 to 8 PSI over the recommended. i think trailers should be at or close to the max rating.

RE: Recommended must have for 5th wheel

Hello, Finally took the plunge and bought a 5th wheel. We have been camping with Class C and travel Trailers for many years so we have all most the stuff. First 5th wheel so we are excited and a bit nervous. I was wondering what specific things we need to buy to make our 5th wheel life easier. Bought a 2021 Solitude 376. Thank you Ours is a Solitude 310GK-R, but you may be interested in our mods. 1. Eternabond roof. 2. Dishwasher 3. Washer-Dryer 4. Sleep Number King Bed 5. 4K Inverter and 30 Amp Transfer Switch 6. Morryde X Factor Braces 7. TST TPMS on Truck 8. Firestone Air Bags and Wireless Compressor on Truck 9. Porter-Cable Air Compressor 10. Bolts to anchor recliners 11. Haier Gas Range 12. Battery Gauges 13. Propane Guages 14. Propane Triple Splitter for Grill and Firepit

RE: Best truck for large 5th Wheel

'My truck's unladen rear axle (hitch installed) weighs about 3470 lbs. My trucks's GRAWR is 7230 lbs. So a pin weight of around 3700lbs should be just fine.' Based on this, it sounds like a 1 ton will have room to spare. I am just not sure if this is all I need to consider. I heard stability in wind and rain may make a dually a better choice. Is there a big difference? I may have to look at a lighter 5th wheel. I have never driven a dually, except for a motorhome. My preference seems to be a 1 ton SRW. Coming from a f150, it is hard to imagine a 1 ton not being enough. Live to learn. Any suggestions on high quality 5th wheels on the lighter end of the scale (15k) loaded? Thank you for all the replies. MC We looked hard at a Solitude 373 and a dually F-350. We decided to go with a 310GK-R and an F-250 with 7.3 and 4.30 axle. It was the right choice for us. We added a dishwasher, washer/dryer, new gas range with convection oven and sleep number king bed.

RE: Oops

After setting the type of brakes you have (electric or electric over hydraulic) you can adjust the trailer brake gain setting. You should probably start with your controller set at about 6. At about 20 mph slide the manual trailer brake lever fully to the left …. If the trailer tires lock up on dry pavement back the setting off … it the tires rotate freely turn the setting higher. The goal is to adjust so that maximum braking can be achieved without wheel lock up. I am often at about 17000 lbs so a little over my trailer’s GVWR and my wheels will lock up at 6.5 on pavement. Thanks. Good info. I will do this test.

RE: Oops

Hi. I have the same weight fifth wheel and run 7.0 on an F-250. Seems fine, but you suggest 6.0. I know there is a test at 20mph. Is that how you set your unit at 6.0? Thanks!

RE: Fuel for Gassers

I believe the 7.3 V8 calls for 87 Octane. It runs fine on 87 when empty. I started using premium when towing and with 22.5K, it is better to have more power.

RE: Size Matters???

Pulling 15K RV with 7.3 and 4.30 axle. During 40% towing, better able to maintain speed than my prior 38K unit with 400 ISL diesel. But, must adjust to 3k to 4K rpm on hills and downshifts. During 60% not towing, gas is much better than diesel IMHO. Mileage depends on wind, but generally 7 towing (22.5K) and 14 to 15 not towing.

RE: Opinions on 5th Wheels with Island Kitchens

DW says our 310 GKR is her "dream" RV kitchen. It has four apartment-quality appliances, a full pantry with door and an island with double sink and modern three tray dishwasher. A friend with a class A was visiting and said that this was in many ways better than the top end class A kitchens.

RE: Grand Design Quality

While we like our Grand Design and think it is good quality, there is one feature that impresses me. The moderators on their Tech page on the Grand Design website are all volunteers and provide great support. I run a business with a product support staff and especially appreciate the value of good support.

RE: How critical is axle ratio?

I think choosing the best gear ratio begins with having a good understanding of your engine’s powerband. Seeing a torque curve of the 7.3 would be very useful. A bsfc map would also be helpful. After getting a sense of your engine’s capabilities knowing the transmission’s gear ratios is essential. Finally knowing how the truck will be used needs to be considered. I don’t know much about the 7.3 other than it has a long flat torque curve and I believe it makes 430 peak hp at 5500 rpm. It makes 425 lb ft of torque at 3250 rpm (263 hp). and 350 hp at 3900 rpm. 350 hp should be more than enough power to tow a 12000 lb rv up a 6% grade at 60 mph. With 3.55 gears and the 10 speed 7 th gear would put you at 2150 rpm at 60 mph with 34 inch tires and 4th gear would put the engine at 3800 rpm at 60 mph. Without giving it much more thought I’d agree with Shiners earlier post: If your going to be running empty a fair bit get 3.55 gears and you’ll have the opportunity to get better fuel economy unloaded on the highway. While towing you can lock out the top gears and still have all the performance you need, seldom dropping below 4th gear in the hills. If your primarily going to be towing with the truck you may as well get 4.30 gears to gain a little bit of grunt at the rear wheels to get your trailer moving in first gear. The odd time when your running empty down the highway you’ll be at 2060 rpm in 10 th gear at 75 mph…. which doesn’t sound too bad. 4x4ORD has good insights. With my truck and 15K fifth wheel, the 3.55 Ford engineer limits of 14.8K and 21.8K are too low. The 4.30 has Ford limits of 18.9K and 26K. These provide a reasonable comfort margin (about 25% and 15%). IMHO, the OP would be happier in the long run with greater towing margin.

RE: How critical is axle ratio?

It does concern me a bit, and I'm thankful for this discussion, because in the near future I hope to be a 2022/2023 (whenever I get around to it) super duty owner. Right now towing a 9K TT, and probably something like a 12-13K fifth wheel in the future. for me, I've made the decision that a 7.3 F-350 makes the most sense. I don't want a truck that turns too many RPMs unloaded on the highway, but I also don't want it to lug while towing. Anything will seem like a huge improvement over my 4r100/3.73 combo right now. I guess it's first world problems when you get down to it. Anybody running 4.30s with a newer 7.3/10 speed, what are your RPMs on the interstate? Does it feel like it's too high? Anyone running 3.55 or so gears? Do you even use 10th?!? I run the 4.30 with the 7.3 gas engine. About 2,000 rpm in tenth gear at 65 mph empty. It pulls a 15K fifth wheel fine, but of course, you know you are loaded. The TFL test was a 16K gooseneck trailer up the IKE, so I knew this would be adequate power. I would get the 4.30 with the 10 speed -- excellent combo. I am rated for 26K, and run at 22.5K GCWR.

RE: Moving to a 5th Wheel

We went through a similar process and ended up with a fifth wheel and an F-250 with 7.3 gas engine. I load the fifth wheel to keep the pin weight between 18% and 19%. For us, it is a good combination of ride and tow capacity. We use about 22.5K of the 26K tow rating. Because DW likes to take day trips, a SRW was required. The 22 foot length is a challenge, but can be managed. The F-350 with 7.3 gas had less payload than the F-250. The F-350 diesel can be bought with 11.4 GVWR and has more payload. Our fifth wheel is a great portable one bedroom unit. DW says she has a "dream kitchen" for an RV. We have six residential appliances, but that means we always have full hookups. We had three class A motorhomes, with a 40DP for 12 years. The fifth wheel has a better kitchen and living room than the 45DP's I looked at in 2019. The big benefit is that our fifth wheel is likely to have about 1/3 the maintenance of the class A. I am more "seasoned" than you are, so the lower maintenance was a big factor. Yes, the setup and unhooking takes longer than a class A, but the living space is worth the effort.

RE: Solar Panels

We are in a different environment, but have a 9K ground solar system and am adding two Tesla Powerwalls with 27K. Check out Ironridge if you want a ground unit. This should cover about 98% or more of our requirements. I am still connected to the grid, but if I were not connected, I would use a generator to cover the other 2%. This is a reasonable solution. I designed and installed most of the components myself, but do have an engineering background.

RE: Air ride assist

I have Firestone air bags on the rear axle and an Airlift compressor. Empty, the PSI is 5. With the fifth wheel, I run at 38 PSI. The ride is much smoother.

RE: Solidtude 390RK

About Grand Design: We have a Grand Design 2021 310GK-R. I added a sleep number king bed, a Bosch dishwasher and Miele washer and dryer. I knew we would add those items when we bought. All the appliances are residential quality. We stream the same ROKU channels as at home on the TCL televisions. It is a June 2020 build and, other than adding a few screws, there are no major problems after five trips. We had a 40DP bought new in 2005 as our prior RV, so we do have fairly high expectations. Our 310 is in many ways better than our 40DP (although it takes longer to set up and hook up to travel). I am very pleased with our RV. CresPro

RE: Air Bag Pressure

Hello, Appreciate all the answers. I have about 300# to 400# RAWR reserve, so this is just a matter of the best ride. With the bags at 5 PSI, the ride is poor. 30 PSI is better and I now seem to like 38 PSI. The truck is fairly level at 38 PSI. I think the best level is from 30 to 45 PSI for the air bags and the best ride. One of the YouTube popular shows for Rv's uses 45 PSI on an F-350 with a toy hauler. Best, Crespro

Air Bag Pressure

Hi, For those of you with air bags on the rear axle and a fifth wheel, how much pressure do you use? I started with 30 PSI and now increased to 38 PSI. About 2,750# of pin weight. Crespro
