It is interesting that there are potentially many bass players on this list.

I have been playing for,, hmmm, close to 15 years?  I spent years gigging
many times a week.  Have had a lot of fun and made some decent money.  Just
like most bass players I am a bit of a gearhead and have been through lots
of rigs.  Among other rigs I keep a travelling rig in the van that includes
an ampeg bass-bus battery powered amp.

I mention this rig because if you live in/camp in your bus and are a bass
player, I doubt that there is a more van-friendly rig out there.  It will
plug in to a cigarette lighter outlet, ac outlet (inverter) or run of it's
own battery for hours.  It fits behind the passenger seat perfectly etc..
here is a link to one, though it looks like it has been discontinued at this
site:
