Hi! Ok, so I don't have a bus, but I thought I could get a lot of hints out of yall because we *did* just buy a used type III ambulance 9the ligths and sirens still work!), which we're hoping to outfit into the perfect road trip vehicle, after much modification, including:

-biodiesel/secondary SVO tank conversion
-pull-out bed
-fridge/freezer/cold storage
-some kind of pooper

any hints on design or acquisition of any of these systems, the more cheap and ingenious the better? help me turn this meat wagon into a land yacht!
