Buying a travel trailer is gambling. You never know what you are going to get. Buying a cheap TT is betting against the odds.
Dutchmen, Keystone, Voltage, and Kodiak (related design, build and sales) have been a significant problem at least since about 2007. I recommend you avoid buying a new one unless you enjoy rebuilding them.
Used ones that have been rebuilt can have better odds. Check out www.Dutchmenowners.org
to see all crying and angry shouting from newbie owners.
I wish you good luck and happy trails ahead!
