Anyone make a mistake buying first MH ?

Talked into buying a "new" rig because it was a better deal overall money wise,instead of the 4 year old one I fell in love with, didn't know jack about rvs other than after 25 years tenting the wife said "Im not sleeping on the ground again". On the drive home,in my brand new, !#@#$%$%$%^, the light shining on the table fell off the wall. It was gone in six months because I was headed for my 3rd divorce if I told my DW one more time, "it's covered under the warranty". Truth be told, I should have turned around and told them what I realized on that first night that it was a POS....nice thing is, the dealer agreed after awhile it was a lemon, took it back and put me in a wonderful rig....
