OK, so I've spent gobs of time reading about weights and trucks and what to do and what not to do. I've noticed many DRW owners have 9 foot campers and many have 11-12 footers, I've witnessed a Dodge SRW 3500 carrying a 1140 Arctic Fox (before options it was 3895lbs according to the sticker) and the drive claimed it road great with just air bags and he was pulling a 30 foot TT (to a dealer from the manufacturer).

I've seen the SRW group that says "10 footer, no problem!" and those who say "popups only!" and frankly, I'm only convinced of two things at the moment:

1. Yes the truck is rated for a specific GVRW. Period.
2. Yes the truck can handle more than GVRW.

I've been in different industries and can tell you that '11, 500lbs' GVRW is a nice round number chosen for a reason. Whether or not that reason has more to do with lawyers than engineers is the real question I suppose, but that isn't what this post is about.

I'm being told by the manufacturer (designer supposedly) of the AF990 that it was designed to ride a 1 ton single rear wheel truck and that all I need do is install stable loads on the truck. I also see lots of posts by people who have big campers like the 990 on SRW trucks who seem to do fine with them. I also see MANY SRW trucks rolling up and down the roads around me with big campers on the back.

So my question is for those who actually do this, that is, those who actually have an SRW truck with a 4000lbs+ camper on the back (AF990 starts at 3010lbs which is under my slide in camper weight of 3370 according to my truck but I know options are going to add around 500lbs and putting water in the tank, propane etc will add another 500 lbs (or so anyway): how is it really? Any trouble? Concerns?

Basically, did you put that sucker on and go "oh ****!" or did you think "too easy"? Let me know if you are a first timer, or old hat too (someone who's never had a camper and sticks a 4000lbs camper on a dually might think 'oh ****' after all.

Thanks

Atypically optioned AF990 will be 4000-4500 lbs once loaded with gear and water. You will be at the upper limits of tires and rims on a SRW unless you upgrade to 19.5" commercial wheels. The actual limit of the axle is 9750 lbs, but the suspension, rims and tires have a lower rating.

I was comfortable with 8000 lbs on my F250 rear axle with 4500 lb rated rims, 4800 lb rated tires and suspension aids to limit sway and sag. Some will not be comfortable going past the manufacturer warranty sticker and others will load up more than I did. I think the AF990 can be used on a SRW truck, but you will not have reserve capacity to tow anything with tongue weight due to your heavy payload and you will be over sticker ratings (but not actual).

Exactly what bedlam said.
My deal was, had the truck already and that part of the equation wasn’t going to change. Bought a single slide AF because that or similar was what I was honed in on and it works just fine. My reaction was somewhere between “too easy” and “oh sht”.

IMO, new long bed srw HD pickup will handle a 990 just fine as long as you realize you need to do a little work to the rear suspension and don’t get sea sick easily! Lol.
Refering to the more pronounced rocking side to side of a srw vs a wider wheelbase. Not bad but not as stable.
I wouldn’t think twice about putting a 990 on a new F350 with a sway bar and some sort of suspension aide, springs, bags, timbrens etc.
All this said, I’m likely a bit more comfortable pushing a vehicle’s limits than a lot of people and I will admit a dually is ideal....for the camper.

I upgraded my f250 with stableloads and airbags and rancho 9000's all around with higher rated tires and a bigger rear sway bar. It is OK for local drives (30-60 miles) on fairly flat ground but I wouldn't go further into the hills with it.

I have been keeping an eye out for a DRW but prices have been out of my range for anything decent, maybe one of these days I will be able to travel further but for now I am happy as I mostly camp on the beach 30 miles away.

What Mellow said. I had my camper on a SRW F350 but there was a huge pucker factor anytime I was on a road or trail that was not perfectly level. Same for the power wind gusts we get around here during the spring - if they hit the outfit from the side you could swear you were going over.

The dually is MUCH more stable - no comparison.

Thanks guys. I have Timbrens now and E rated tires (though looking at new Toyos which have a higher weight rating) and ordered Tork Lift Stable Loads to install before picking up the camper (if we buy it).

I had a Fleetwood Angler 9D which I am guessing was 1500 lbs lighter loaded (it had a dry weight of 1680 according to the sticker and little to no options -- not even a radio) and it squatted the truck 1" total and wasn't a problem at all to haul even offroad in rough terrain. I also pulled a 3500lbs sawmill behind it and loaded the back seat of the truck with a couple hundred pounds of gear and the camper too (and the mill).

This was my setup then. I'll still need to pull the mill and can add more gear to it vs inside the truck/camper but I want more headroom in the overcab 'bedroom' and am a big guy (250lbs 6' tall) and need a bigger bathroom. I use the camper as a 'home' when I am out on milling jobs and bought the F350 so I could pull the mill into various offroad locations without much issue. Won't be changing the truck too soon but might in a couple years or 3 if it really doesn't work out.

Your rims may be rated lower than those Toyo tires and not give you any benefit in just a tire upgrade...

My previous set up was a 2006 SRW F350 6.o diesel with an AF990. Added Stableloads, Sumosprings, KYB shocks Torklift tiedowns, and a superhitch. Towed a boat with it. Heavy, but manageable. Never had a breakdown or issue. Would have been much better with a dRW.

2016 Ram 3500 SRW Laramie.
Truck weight full of fuel:
Steer axle 5100
Drive axle 3200

With Bigfoot full of water and nothing else:
Steer axle 5500
Drive axle 6680

Loaded heavy for 2 weeks, heavy clothes, full of water:
Steer axle 5540
Drive axle 7120

Oh ****. RAWR is 7,000 and payload is 4018.
I drained water down to 1/3 tank and rescaled.
Steer axle 5520
Drive axle 7,000
I'm still over payload by 102# and GVWR by 220#.

It drives good. I added a Bigwig and really couldn't tell a lot of difference.
More attention needed regarding what I pack.
Edit add...rubber bed mat and 5/8" plywood under the mat.

Hmmm wonder how I find out about the rims? They look like stock rims to me (18").
