Couple of comments based on full time trailer living for the last 9+ years....and "heavy" weekend camping for 50 years.
Started with 1997 Kit Sportsmaster "weekend trailer" 5ht wheel for the first 6.5 years. This trailer had been lived in full time for all but 1 year of its life until I got it. Even though they are easy to pull and would probably be pretty good for weekend camping, they are poorly made as are about 90% of the trailers/5th wheels available new or used. Must be willing to do a lot of maintenance - not good for full time.
Moved to used 2007 NuWa Discover America in early 2014. Excellent trailer - but they also have issues to watch out for. Mine had been shipped from the factory without two pieces of foam in the generator compartment that allowed massive cold air intrusion until I plugged it. THEN it was a 4 season trailer!! If you can find find a good used one from before they shut down, it will be a jewel and will serve you well - even if it takes some 'remodeling'. And their prices are rising because that is so... I don't know about their new built stuff - haven't tried one yet and wouldn't even think about them until I know who is building them for NuWa now. Did great for me until destroyed in a tornado on 6 May in Oklahoma City, along with about 65 other RV's. Sad face...
NuWa, Excel, Teton, old HR....any or all would be worth consideration for full timer after remodeling and would likely give much better service than any of the new ones you could buy.
Then to a 1995 Fleetwood. Absolute junk, as all Fleetwood stuff is, but was able to use it for a while. With these cheap trailers you can make a go of it IF you are willing to do all the rebuild on the fly that is necessary. I do that, 'cause I am cheap and cannot afford a DRV.
And now, back into the original 1997 Kit. Have been working on leaks at corners, replacing wood and interior panels. Reaches a point where ya just can't keep up. May have to just build my own trailer to get what I want in features and dependability!! OR find another Discover America!
Observation from watching hundreds of RV's come through the RV park for 9 years and talking to people. Open Road REALLY sucks!! See more delamination on those than most others. ALL trailers made now - most of the corner seals on both fiberglas wall and metal wall are very bad if they use the butyl tape - guaranteed to fail and leak in as short a time as one year! Watch closely and try to stay ahead of it...not if it will rot, but when it will rot.
Transmission work on the truck - Blumenthal's in Oklahoma City appears to have a national reputation and I have seen the results of their work. Very good. There have been probably 50 rigs come through to stay for days to week just to go there for work when needed. A handful of these come through and stay at the place every year, so get to see the rigs repeatedly. Couple of DRV, Teton, one NuWa, and a couple of cheap trailers, too. They also do engine work, but nobody I have talked to was there for engine. If even close to transmission work, it's good.
Dexter is excellent - I have several torsion axles on other trailers....work trailers.
Pulled all of mine with '99 Dodge Ram 2500, 5.9L, auto, quadcab, long bed, 330,000 mi. Still do... Have to slow a little on hills but not unreasonable.
