The ideal vehicle

[comptiger5000]

You tow it behind an RV with the Transfer Case in Neutral, not the tranny (t-case in N de-couples the tranny output from the driveshafts). Being that the transfer case has no synchros, you could get it out of gear while moving, but you'd have to stop to re-engage it, which is somewhat unsafe and impractical. If I had a really expensive, sychronized t-case swapped in, such as an Atlas, then that would work great!
