I've worked & wrote collision estimates on these small buses in the past. Most of the time they were church buses converted from used school buses. The most usual repair estimate I wrote was due to low clearances in fast food drive throughs. 13' doesn't fit under 10' very well!
You could also keep them in the bus when you weren't out actively searching so your spouse wouldn't complain (as much) with all the new sets you've bought.
When are these supposed to be on the market, anyway?
