Max --- I can't speak to the issue of construction. I am writeing to say make sure the floorplan is the one that fits your needs, or you will be looking for something else in a couple of years.
I know one couple that bought a camper without thinking about how the floorplan will fit their needs and have ended up buying two other campers since their first purchace
My wife and I took almost three years to pick our first camper. Although our kids are grown, we have grandkids we take camping with us. Should we buy a bunkhouse camper or a floorplan just for the two of us. We decided that the floorplan for us was best and when we take the grandkids they sleep on the pull out sofa, works best for us, as we do most of our camping as a couple.
JMHO. Good luck with your search
