People today have been conditioned to not even perform simple repairs or perform needed maintenance. We live in 'plug and play' society now. If it breaks, do a couple things, whine about it on the Internet or take it back and expect immediate repairs and satisfaction or toss it in the garbage and relegate it to a landfill.
Consequently, when a sub standard built RV has issues, they do the first 2 because tossing it in the garbage isn't an option because it's usually accompanied with a fat payment book.
Being an old, old time RV'er, I knew going into a newer unit that I would most likely have some issue and I was very pleasantly surprised when I did not, but I also suspect that I'm in the minority. My unit is 3 years old now, built just prior to the push 'em out the door as fast as possible industry credo today.
I would not even consider a new unit today because the industry is stretched so tight that quality is second to production. Build 'em cheap, stack 'em deep and sell 'em for what the mnarket will bear.
Gotta love it. Keeps forums like this one alive with issues.
