sw,
I like the way you think. After reading this post thru and thru, I couldn't find what you did with the rear suspension to take the added weight. Does it have coil suspension? I'm used to big 'ol leaf springs and this is one of the first RV's of any size that looks to have coils. How did you approach that?
This would be an ideal rig for stealth camping along the way while traveling. We're planning a 4 month odyssey around the boundary states (U.S.), not in the summer time and would like to paint the whole rig some other color than white. In fact, I like your color choice for blending into the urban jungle. That or Mountbatten Pink.
I sure like your ideas. The LX450 is such a full-featured luxo platform on which to do a build.
regards, as always, jefe
