not on your own, answer will come and go, but us thread watchers LOVE pics. whether it be examples of ideas or such. just a heads up, but there are some pretty good build threads around, even for just suspension ideas, body ideas, so forth. CORPO(believe is his name) building a killer dually truck that you can scope out and put to thought. guy is a madman with his thoughts and frame building! im playing around with air bags and posted pics as there available on my build as well. could also make yourself a double dually axle set up. kind of like a miniature diesel, if your going to tow, just for thought.
not to sound all over with thoughts, but airbags are easy to play around with and they have very user friendly parts. as well with link suspension. im by no means an expert, and many will soon chime in with advise or links possibly, but def a cool idea you have pointed out. the motorhome frame and additional axle like i said would be slick.
