Tips on what's for me??

[SoulFire]

I'm going to convert a School Bus into a band-mobile/home with pretty minimalistic amenities. I plan to install about 12 bunk beds, a small kitchen area with a stove and fridge (probably run from propane), some lighting and power outlets. My questions are:

What are the most reliable/least problematic models of buses to look for?

I would eventually like to convert it to WVO, does this change the style of bus I should look for?

Thanks guys,
Cooper
