The only thing I know about Keystone products is from reading a blog where the people had MAJOR problems with their trailer. Keystone stood behind them, but they had to drop off their trailer up in Indiana (I think) for months and months at a time while they put on a whole new side!
The last time they put on the new side, they were supposed to put on both sides, but didn't. They were then going to have to empty the trailer again (they are fulltimers) leave it with them for months AGAIN.....and wait for the repair.
They opted to trade 5th wheels and get a new one. NOT a Keystone.
You can read their blog
hereyou may have to search through it to see where they talked about the problems with the trailer, or you could email them for more info. That alone is enough for me to never buy one of their products.
