Maybe. Maybe not. My grandfather's 1985 Dodge Ram ran for 30 years without needing major powertrain repairs. No other Dodge in our family since then has gone even half that long and I wouldn't have confidence that a new one would either.
(some brands listed below are in related markets - such as buses or boats - rather than RVs per se)
My grandfather's Plymouth 60' model was retired in the 80's. The point to be made however was it was retired with less than 90 grand on it.
I have only purchased two travel trailers new (my first one was used), and from that small scope of an experience I can say the cheaper travel trailer I purchased in 2008 was built with greater quality than the more expensive one I bought in 2021. The first was a 17ft trailer, no frills that slept 5 with a queen bed which turned into a dinette and two bunk beds. Other than doing a little caulking here and there it was a great trailer and we did a lot of trips in it without any issues for several years all accross the US. In 2021 I bought a new trailer which looked superior with more amenities, it was 21ft rather than 17ft, slept the same, but just looked a lot nicer, had more cabinet space and was still a lite series easy to pull, but I have had to fix a lot of stuff on it, for example: the door wouldn't open after driving in the sun because it was fitted too tightly (had to remove the striker, grind it down so it would not catch the latch once the metal expanded and reinstall), the GFCI outlet quit working on the first trip and started blinking red (dealer reaplaced it under warranty), one of the wheel wells was missing sealer for about 14 inches and you could see a 1 inch gap where water could just come up into the travel trailer if you went through a puddle, cabinets appeared to be caulked with mud, that you would use for sheetrock, and not only did it look horrible, but pieces were falling off while driving down the road, door trim for the bathroom fell off after the first few trips and it wasn't cut to proper length, ceiling trim fell off after a few more, the refrigerator door fell off when I openend a few trips ago, the sewage pipe was held by a thin metal strap which broke and dropped the pipe down about an inch off the ground during the first trip as well, the sealer on the roof was cracked and large chunks were missing in several areas which I had to reseal, the sheet metal screws at the base of all the siding outside backed out (lost some of them), so I added silicone and reinstalled them to make sure they didn't back out again, and I will stop there, but there is more. So between the two trailers I have purchased, there was a vast difference in build quality when considering my 2008 trailer versus my 2022 model trailer, although they were purchased from the same RV dealer (the components in the new travel trailer are fantastic, but the quality of how they built and installed them in the trailer is lacking). I am happy with the new trailer, but being new I didn't expect to put in the amount of work I have had to do, its great now that all the bugs are worked out though.
