More derail! Apologies all...
Call some construction contacts and ask for pricing on office trailers. Home is what you make it. Should be far cheaper and less likely to have hidden issues. Modern travel trailers are like flip houses. Pretty finishes hiding the horror underneath.
While I admire the thought, the reality is that keeping something liveable for a couple and two dogs and is also towable under 5000 lbs just doesn't line up with construction trailers. They're much more solidly built, but definitely not cheaper, and definitely definitely not lighter.
More importantly, I have spent way too many hours, days, weeks and months in the bloody things smelling BO, fish lunches, farts and other horrors, and so have zero desire to spent another minute in one if I can avoid it.
Build quality sucks. Goggle delamination.
We sold our 26 footer cruiser for the same reasons you listed. It would be cheaper to hotel the same number of weekends and get a variety of locations. That said, hotel rates have exploded recently and restaurant meals are up there too.
100% with you on the build quality, though apparently the newer ones with Azdel or similar go a long way to minimising the delamination issues. They still have horrible plumbing with improper fittings, leaky roofs, thermofoil counters that swell when shown a picture of water, appliances that last about a year before blowing up, China Bomb tires, and on and on...
And you're right about hotels, but holy smokes have they gotten expensive over the past few years. The reality for us though, is that a huge part of the appeal is staying somewhere in the woods. Our preference is electrified provincial park sites for the balance of wilderness and comfort.
As for build quality, pretty much all the mainstream boxes on wheels are built like total trash and should be valued at less than half of what they seem to command, however there are still some quality RVs out there….but they are not cheap.
We own a Helio now - really only good for two but insanely well built and will still be around in 30-40+ years. There’s also bigger options out there that are built good like Casita and other fibreglass clamshells, and I’m hearing good things about Brinkley in the 5th wheel category. But again, not cheap, and people seem to want cheap vs good anymore.
I'm sort of on the fence here. There seems to be two tiers of RV construction, the budget stuff built by the big makers (anything Thor, Winnebago, etc.) and then the higher end stuff with better build quality, like Lance, Intech, and all the fibreglass builders. But I think on a base level, the actual construction methods and materials used by the cheaper guys aren't inherently flawed (at least for the Azdel units mentioned above - the tin ones are a disaster waiting to happen), as there's only so many ways to keep a trailer light and cheap. The issue I have with the industry is that their QC is so terrible. How does a trailer where the shower drain isn't connected get out of the factory? Or where the screws don't line up with the frame so the roof flies off on the first windy day?
That said, if you get an okay one, and accept that things will need fixed on a regular basis, they're not that bad. I'm not convinced spending more than double on something like a Lance is actually better value, as they have similar inherent construction issues. Most of them are so simple that most bits are modular, and doing repairs is easier than home DIY. As long as the walls are fibreglass and the frame is aluminum, you can always replace the bits that need it.
The real exception is the the fibreglass clamshell units you mention that last forever. But they also cost 3-4 times as much, and dropping $100k plus on a smallish travel trailer starts to make the math in my post above look really kooky...
