I've always wanted a class B. The Mercedes Sprinter chassis is a V6 diesel and gets over 20 mpg. It's a van conversion so no worries about leaks, gel coating care, easy to park, easy to drive, last forever and hold a decent amount of resale value.

I've traveled America twice, once on a bicycle and once in a Ford F150 with my son. When I went into Yosemite and Yellowstone national parks they were always crowded and parking was a problem. A motorhome would be hard to manage on trips with multiple destinations. You really have to plan every movement.

Good luck with your search and safe travels!
