It's interesting how different folks view camping, and how the progression often works. Myself, I still prefer tent camping backpacking style, but age, and the wifes hip make that a poor option for us most of the time. For national parks etc. I had a tent trailer, then went up to a class A which I found I didn't really like. In the sorts of areas I could take it, it seemed more easier to just motel camp. Next came a 19ft travel trailer, which could get in to most places, but the wife thought it cramped so we stepped up to a 25 foot TT. For the most part, we only use it for Forest service sorts of camping, and find we end up finding motel camping more to our liking for hitting the city sorts of trips.
The bad thing is, when you "Buy Local" It often doesn't mean it's a local produced product. This year when buying the little bundles of firewood at a store near where we were camped recently in both Utah, and Colorado, it turns out the wood came from Montana. Go figure...
I'm not a fan of Politics of progressive insurance, but wouldn't necessarily let it keep me from buying the insurance if the business practices were good. Based on what I've heard from friends that used Progressive though, and documented customer service like the following keep me from even thinking about it.
Progressive goes to court against their customer.
Actually, his rzr was well configured, the custom cage held up well, and with a little more experience he should make that one next time. A little better approach angle and he almost certainly would have made it. Even in the situation he found himself in, he had a sporting chance or rolling out had he backed out of the throttle a little and nosed her back downhill. He needs to re think the helmet he was using though. I'm not sure what it was he was using.
Having participated in hard core off roading of trucks for years, and the last 4 years or so with a rzr, that was a climb many would attempt. Yea, sometimes your results are somewhat exciting like what happened here, but for those involved in the game, re-building the machine and making it even tougher and more capable is part of the fun.
One thing for certain (we just spent a week in Yellowstone and stayed in FSCG, my sixth trip since the 1980's) that park looks NOTHING like the original developers viewed it when they protected the land.
Far as I'm concerned, the development has gotten way out of control, and the crowds unbelievable. NO WAY can we protect this park from the "progress of cell phone, FHU, and eventual destruction over time". And that is truly unfortunate.
If and when we decide to truly protect these national park and forest lands, we can only do that if we return to more primitive style campgrounds. Only that way, can the people that visit Yellowstone and other parks understand the original intent of wilderness protection within the national parks and forests systems.
Given the sheer size of the human population, and the resulting large number of people trying to enjoy the "outdoors", it isn't possible to keep things as they were without banning people or at least significantly limiting the numbers that are allowed into the "protected" areas. Kind of a catch 22. We desire to preserve the beauty, which can only be done if we prevent ourselves from seeing and enjoying it.
Having explored and enjoyed so much of the backcountry areas for decades, I'm amazed at how many people now venture out, and how many areas now have lottery permit systems to allow visitation now. As a person who often attends land use discussions, I anticipate that camping, and venturing into the back country are something that will change significantly in the next 20 years or so.
Finally, back to the cell phone discussion, I still find that at least a third of the state of Utah still doesn't have coverage, and we don't miss it at all. Of our camping trips this year we only spent about a fourth of it in areas that had cell phone coverage. It's kind of nice in that we don't get any "work" calls, and don't have to feel guilty about being dishonest when we say there wasn't phone coverage available.
Sticking to the original post, you can indeed tow double trailers on ball hitches in Utah provided you don't exceed the max length limit. You can even tow them at 80mph and be legal provided you're on one of the sections of freeway where that is the posted limit. That said, 80mph with the little tires of those trailers, and of course doubles being somewhat more prone to sway might lead to a little excitement. Since you live in Utah, I'm sure you have seen a lot of doubles being towed, in fact, about a third of the folks we regularly camp with do it, and couple using 5ers, the rest bumper pulls.
I towed a very similar setup for many years without any issues. Tow vehicle was a 87 2 door S-10 blazer, 3 inch lift, hopped up 3.2 crate engine. Trailer was a coleman tent trailer, lifted on a custom suspension with a heavily beefed up frame I customized for off roading. I had a little 16 foot aluminum boat on a trailer that I'd carry the 9.9 hp motor and 5 gallon fuel tank in when traveling. It towed really well, and I could even back the combo up to launch the boat with the trailer still attached more often than not. Without the boat I could take that truck/trailer combo almost anywhere. I even did the Shaffer trail with it when I was camping on the white rim trail in Canyonlands.
If you're in northern Utah, there are several trailer manufacturing shops that can look over your trailer and custom build you a receiver setup if frame is solid enough make it feasible.
You didn't mention if the cummins had a turbo or not, but I'll assume it's a turbo. One possibility might be the fan not pulling enough air across the radiator. As air density decreases, the fan will pull less volume for any given RPM. It's been to long since I took my aircraft powerplant classes back in the 80's for me to remember the formulas, but it seems a fixed prop lost about the same amount of power as an engine, which you could get pretty close to calculating by figuring 3 percent per thousand feet.
All that said, I've never noticed what you're experiencing.
Even cell phone batteries still cause fires from time to time, although it's not nearly the problem it was a few years back. For really impressive results though, you need to be flying an RC aircraft you just spent weeks building, and have it vent on you a couple minutes into it's third flight. It's impressive and exciting to watch, but at the same time you can't help but think about how much time and money just went into that little fireworks display.
We have a 2012 Timber Ridge 240RKS, and I must admit we've had quite a bit more trouble with the cabinets and refrigerator than we've had on any previous TT or motorhome. My best guess would be that we've put a little over 12,000 miles on the Trailer since we got it, so we probably do cover a little more ground than many, but are far from extreme. Surprisingly, although we often travel dirt roads, most of the problems seem to happen with pavement travel.
The shelves tend to come out of the slots in the refrigerator even the ones with nothing on them, and then they are really wedged in tight and hard to put back. I'm surprised we haven't broken the walls on it yet. The rear cabinets have to be packed with pillows and lots of support bars. The cabinets being quite flimsy have also been falling apart with the screws backing out, cross braces breaking etc. This is part is because Outdoors RV went really cheap on the cabinet construction when compared to the Springdale trailer we traded in on it, but it also seems things are really getting bounced around. While I really like the floor layout, the rear of the trailer does seem to ride rough on the road and thus I'll probably look to have the bedroom in the back should we do a next time around. The kitchen we'd look to have in the middle like the last TT, or up front.
That said, having just come back from a trip, I need to go out and do a little work on the kitchen cabinets under the sink where they're falling apart from the bouncing.
