RE: Tires and Wheels

Ordered the Vision Hauler 81 Wheel 19.5x7.5 8x170 Matte Black today. Now the tires. Currently leaning towards the Toyo M608Z 245/70R. People here to give Toyo's great reviews. I don't put but 10k a year on the truck so I'm hoping they'd last quite a while. Anyone with experience on these or suggestions on others in the 19.5" G or H load range? Live in the Northeast so need all weather. Take the camper out on the beach a fair bit and plan on doing a bit more off the beaten path camping in the next couple of years. Also have at least one cross country planned. I ran those tires and got 60,000 miles out of a set with a 3000 lb commercial cap in the bed and they still had a few thousand left when I sold the truck. Make sure you have a good shop do the balancing, it took my local Les Schwab a few tries to get them balanced, one other thing I had bad wheel squirm and tracking the grooves in the pavement for about the fist 6000 to 8000 miles before they settled down. They were great in the rain snow and ice but so so in mud.

RE: White Out in Sierra Nevada

I remember living in South Lake Tahoe in the winter of 1983, we got 65” in a 24 hour period and had about 168” in a three day period, we were climbing out second story windows that year. We ended up with over 44 feet of snow that year.

RE: Propane Problem

What are you connected to? I would make sure the regulator is correct.

RE: 60a DC-to-DC Charger Powered by 220a Alternator

I have a digital volt meter to keep track of the truck voltage, it runs between 14.4 and 14.6 volts, I have driven up to about five hours straight and it never changes.

RE: features for dc to DC chargers

Yes it is in the manual, I just noticed they make a 25amp dual input model as well.

RE: features for dc to DC chargers

The Redarc 40 and 50 amp dc to dc chargers have a built in solar controller that use solar charging first and then supplements with alternator charging, might be a useful feature for some.

RE: 60a DC-to-DC Charger Powered by 220a Alternator

Also, a major wiring upgrade will be needed. This is how I did it I VEHEMNTLY DISAGREE ! The whole point of a DC-DC charger is to NOT require oversized charging cables ! It boost the voltage at the RV battery to the correct voltage to charge the battery using the standard vehicle/trailer wiring ! Even with your large gauge wire, you should check the voltage at your campers battery after about 10 minutes of driving and at high idle. If the battery is say 80% SOC, the voltage at the camper battery should be >14.0V. I think some of your info is not accurate, you keep talking in these threads about smart charging and the ECM controlling voltage and now engine RPM. You have been stating that you can’t use vehicle charging effectively because the charging system will lower the voltage after a few minutes to 13 volts or so, now I will state here I don’t know about Ford or Dodge/Ram but all of my Chevrolet HD trucks since 2003 do not do this, the alternator keeps voltage steady all the time, I can drive for hours and it never changes. This has been on four different Chevrolet trucks including a 2003 2500 HD gas truck and three 2500 HD diesel trucks, 2009, 2013 and 2019, so when you are making a blanket statement that something will not work because of smart charging you are misleading people IMHO. Also as stated before in this thread all the dc to dc chargers I looked at for my install recommend larger wire from the vehicle charging system, now admittedly I was only looking at 40 amp or larger dc to dc chargers. I am not trying to start an argument just stating my experience with GM HD trucks.

RE: 60a DC-to-DC Charger Powered by 220a Alternator

I am running the 50 amp Redarc and everything has been working great. I am adding another pair of batteries and another 50 amp charger for 100amps total. I also have the snow plow prep on my 2019 Chevrolet with a 220amp alternator.

RE: Built-in Genset on 2021 F-150

That is basically what I am setting up on my truck, 100amp charging from the truck, 675ah of batteries and a 2800 watt outback inverter. I am using it to power my commercial cap and truck camper when I get it. I can use the remote start and get charging from the truck for using the a/c or larger loads. Sweet. Recommend using a catastrophic failure type fuse on the input to the inverter. Maybe a 250 amp...ish. Yep outback manual recommends 250amp fuse, I also have a fuse on each pair of Trojan T-105s.

RE: Redarc DC-DC Battery Charger

They work well, I have been using the 50amp model and it has been the only charge source to run my portable compressor fridge, charging batteries for my work tools and other 12 volt loads. It is working so well that as my power needs increase I am adding another 50amp charger and two more Trojan T-105s.

RE: No hot water during a freeze

Hot water will freeze before cold water. That is a myth It's not a myth. It's basic high school chemistry Then you slept thru your high school chemistry class. Still water freezes at 32 deg F. Remember that from your high school chemistry. So what it takes to freeze water is to drop the temp from its existing temp to 32 deg. That requires a transfer of heat away from the water. If the beginning temp of the water is 60 deg then it requires a transfer of 28 deg to drop the water to freezing. If the water is 200 deg then it requires a transfer of 168 deg. That is simple high school chemistry. You flunked your class. Stay after school. Re-read the chapter on heat transfer. Do some extra credit work and maybe you'll pass chemistry this semester. So what happens if there is less water, does it freeze faster? I won't even bother to explain why hot water freezes faster because I don't think you would understand anyway. The idea that hot water freezes faster is a known phenomenon. It's not an idea that just came along within this thread. Aw come on my small brain might grasp it if you talk slow. A smaller mass will lose heat quicker and freeze faster as it will have less stored energy than a larger mass. I have seen and learned a lot in 32 years in plumbing and hydronic heating, most of the time hot water lines freeze faster and first. I have thawed and fixed hundreds of frozen pipe jobs so that is real world experience.

RE: No hot water during a freeze

Water that has been heated will freeze faster than cold water, it has less air entrained in the water than the cold. What if you have 2 pans of water, one has been heated, but both are now the same temperature. Will they now both take the same amount of time to turn to ice?No and it has nothing to do with air in the water. See my 10:12am post today. What do you mean No, even the article you referenced says they don’t understand why, do you have some credentials or experience you want to share? I am not saying hot water freezes faster but water that has been heated and has cooled off afterwards in the piping. Mpemba-two-water-probes.svg The Mpemba effect is a phenomenon in which hot water appears to freeze faster than cold water. The phenomenon is temperature-dependent. There is disagreement about the parameters required to produce the effect and about its theoretical basis.

What if you have 2 pans of water, one has been heated, but both are now the same temperature. Will they now both take the same amount of time to turn to ice? Have never tried two pans, the difference would obviously be a pressurized versus non pressurized test which could have two entirely different outcomes. I do know in my 32 years in plumbing and hydronic heating that hot water lines can freeze before the cold. I worked in plumbing and heating in South Lake Tahoe and have probably over 1000 hours running a pipe thawing machine and in my experience 90% of the time it was the hot water side that had the most freezing and pipe damage. You guy’s can argue all you want about why but I am giving you real world experience.

RE: "Newer" Ford trucks don't charge house batt's?

My 2019 chev puts out 14.4 volts all day long, that is one of the reasons I went with a DC to DC charger, I can drive up to six hours a day for work and didn’t want to cook the batteries. With the 50 amp charger I have not had to plug in to charge, In fact I don’t have any other charger hooked up yet. I run a compressor refrigerator and a 300 watt psw inverter in the cab as well as battery charging for my work tools. I am adding two more Trojan T-105 batteries for a total of six and another Redarc 50 amp charger for 100amps of charging. Inverter/ charger box

RE: "Newer" Ford trucks don't charge house batt's?

I would check the wire gauge on the factory charge wire, the one on the chev is too small to do much. I ran a new 1/0 100 amp charge wire from under the hood and am using DC to DC chargers with four Trojan T-105s. The Redarc DC to DC chargers work great, I am going to run two of their 50 amp units in parallel, they also incorporate a MPPT solar controller that the unit will give priority to if there is solar power being generated.

RE: Small PSW Inverter

I am satisfied with my Samlex 300 PSW. Anker makes excellent USB chargers for cigarette light user. True to form Orientals make true garbage power connectors. A Blue Seas marine plug and socket fed by a dedicated TEN AWG cable and 30-amp fuse I'd the ideal power feeder. Just make sure you get pin terminals if you go bigger than 8 awg, I found this out yesterday. I had to install the inverter about 6’ from my cab connections under the center console and they recommend 6 awg, guess what 6 awg will not fit. Just use 6" of #8 as pigtails and then go #6 from there. Various ways to joint the #8 and #6 ends. CAUTION! DO NOT insert the stranded bare end of the cable directly into the tubular hole as the set screw will not pinch all the strands, resulting in a partial / loose contact and consequent overheating. To ensure firm contact, use suitable pin type terminal similiar to the termi- nal lugs provided with 2 types of detachable DC input cable sets provided with the unit (See Section 8.4.7). I thought about doing that but the instructions say not to put stranded wire into the terminals, and after looking more closely I can see why, the set screws are really small and will not clamp all the wire so half the wire is loose.
