How to tell a quaility RV

I'm not a handyman by any means.....but I can tell when I step into most rigs. If the cupboard doors wobble wobble when you open and close, if the mouldings don't line up or are falling off (seen that in brand new rigs), if shower door is flimsy and doesn't seem to line up, the drawers are stapled together....badly, and if the outlets are set in crooked or the hole is showing around the outlet cover .....is ALL a sign to me. Yes, I've seen those mistakes (or lack of caring in new rigs). Don't be afraid to open and close EVERY cupboard door.... I saw one that looked so good for us, then opened the cupboard doors in the kitchen. They had NO cupboard space. Two of the doors actually covered the plumbing....NO place to put fry pans, etc!!!!!! If you REALLY look a rig over instead of looking at the pretty curtains or the glitz, you can tell. BTW -- a toyhauler we looked at one time had a hole in the bottom left side in the garage.....the hole was big enough for an adult to crawl thru. I asked what it was for....the vent the garage. Hmmm a small vent would have worked. The hole didn't have ANY moulding around it besides being a GREAT way for someone to break in and steal from you. Ironically, it also showed us just how THIN the wall was!!!!!! One sheet of wall panel and the outside covering.......NO INSULATION!!!!! I think that company went out of business.
