Try 180,000 miles. Before you holler no way
like I did...Some folks pulled in next to us and had same trailer brand as us but much older. Got talking with them, I asked how many miles and he said around 180,000. I said "no way!!!" his wife heard me and went and got her "Journal". They live on west coast and visit their kids twice a year. One in NJ and one in Alabama. She had their towing miles figured out using google maps. They got their truck and trailer when he retired in 1996 and put 225,000 miles on pick up before trading truck in a new one. They have had (only) 3 blow outs. and on their second hitch that goes over the hitch ball. Lots of other wear and tear items. Fridge has been replaced, some woodwork and shower. Overall trailer looks real good. Only delamination is where a RV place replaced a window frame and didn't do very good job of installing it. They had to get a new roof and stuff on top when a hail storm did damage several years ago.
She said, they look every year for a replacement but find quality and more plastic than they like, so keeping old one.
After seeing her Journal, and seeing what it was handy for, (and not just mileage) we thought we would start keeping one, but haven't started yet:o
Anyway 180,000 miles.
