Lazy Daze '96-2000 26.5MB, 26.5RB

No chance of me going with a Tiger or Sportsmobile. Too confined. As far as roads are concerned, I'm not planning anything far off the beaten track. The motorcycle (Yamaha TW200) I referred to in my post is intended for that purpose. This is going to be an open-ended trip, at least 2 years, with long stops along the way, so the motorhome has to provide comfort. At 68, that's important. I've been advised by a guy who leads the TrekAmerica Mexico to Argentina tour that anything larger than a 30' Class A will be a white-knuckle PITA. A woman who blogged about driving through Mexico in a 36' Newmar was less than thrilled with certain moments of the experience. Highways frequently are hilly, narrow & precipitous, and pass through small towns with very confined roads. If I can avoid a widebody Class A in favor of a Class C with enough CCC, I'd prefer that. I have a fairly stringent set of criteria, and have scrapped more than one seeming possibility which failed to meet one of them. Thought I had settled on a Safari Trek '91-'94 on the Isuzu/NPR platform, which is slow as molasses but bulletproof, and has an exhaust brake. Inadequate CCC. My main interest is learning the CCC of Lazy Daze on the E450.
I have considered MANY possible alternatives. Still doing so.
