We've been living in our 29.5BHOK since late Jan, (3months so far) and will be living in it a LOT.
Quality could be better, but, at the price it is good. There are some things to be careful with, such as door hinges (don't put heavy things on the door or hang from them like you can in a stick house). A couple of water leaks where the fittings were not tightened properly (seems to be a common problem on all the Jayco series). Had some wiring that needed to be fixed.
Insulation is really pretty good. Our first month we saw temps in the 20's (and a couple nights in the teens). We went though a tank of propane in 4 days at those temps. As soon as the lows were above freezing a tank would last a week (FWIW, there are two tanks). Better than my previous fifth wheel which had little insulation at all.
Contrary to some, we like the bed. We always put a synthetic 'featherbed' on top of our mattresses and the Simmons has been great. But, we like soft beds.
If you are going to tow a lot get a 3/4T. These trailers are not that light (loaded, ours hit the scales at near the GVWR of 11,000lb).
If buying now make sure to get the Goodyear Endurance or Maxxis tires. I am replacing my Rainiers with Goodyears next week.
We did replace the sleeper sofa with a 'theater' recliner set. Much more comfortable, but, not cheap
We didn't need another sleeping area but we did want comfortable TV chairs.
Best thing for us is the bunkhouse we got. It is our 'hobby room' with workbench and storage.
So far we love the rig.
