If you want the scoop on what RV's perform and last the longest?
Go to a dog show and look at what brands are parked in RV parking lot. :B
We put thousands and thousands a miles a weekend on our MH's. They are driven hard and put away wet only to head out again the next weekend. Repeat the process 365 days a year.
They keep their MH's for well over 100,000 miles also. And then sell them to another show person just starting out in RV'ing to dog shows.
So we see a lot of MH's every weekend still up and running approaching 200,000 miles! Can't beat being able to talk to thousands of RV owners and see their MH's to get the scoop on which one is the best.
OP: MANY dog show people switched to the Sprinter when they came out. Mostly handlers who are 'on the road literally 365 days a year' driving to shows. When I was thinking of downsizing I asked all of them how they liked the Sprinter. Every single one said they loved their Sprinter, performance, durability, drive ability and gas mileage.
