My wife and I had bought a TT, a particular model my wife found - not Keystone, and I don't think it matters, from a dealer about 200 miles away. Of all stupid things, the bathroom vent fan burned up the first week we had the trailer. Of course, I could have taken it the selling dealer, but that sure didn't make sense because the part probably costs about $15, and to tow the trailer 400 miles round trip would have cost me about (10 mpg, $3.50 per gallon, 40 gallons) $140. The manufacturer said there was a dealer about 140 miles away, so great, I could save $30.
Ended up talking with the manufacturer customer service, the guy sent me the part, and I fixed in about 15 minutes.
I told my wife I would never buy an RV from a dealer so far away again!
So, this time I bought a Keystone from a dealer 100 miles away - Now I need to see if that makes sense.
But we can do 100 miles, we liked the Cougar, and they were the closest dealer.
