They seem to have a lot fewer issues than most trailers....especially PUs. We moved up to a TM this year and we are thrilled with it. The only thing that we miss is the great big windows in our Coleman Tacoma PU. We love the recirculating toilet, shower and 30G holding tank. The fridge is far superior to our Coleman fridge. Set-up time is about half of what our Coleman PU was ad a heck of a lot less strenuous.. I also love the fact that we can pull off the road, pop-up, have lunch in our trailer then go on our merry way. Couldn't do that with our Coleman PU.
Value is relevant to the owner. Mine is a great value to me because I can store it in my garage. That cuts down on wear & tear and storage cost. They tow real well and have about the same wind resistance as a PU (In fact....they are a PU
).
Water heaters, furnaces fridges etc are the same as you will find in most RVs and subject to the same issues.
The lift system is a lot easier to use and a lot more reliable than a canvas PU.
