Looking good. While its the wrong color, you could always add the "Transcon Medi-Vac" out of Cannonball Run! There is the group of people you would know! 👍😁
I would put some solar panels on the trailer have have a way to plug it into the Ambulance. and then you could put another 6 batteries in the trailer for extra storage.
most who buy old buses Or Retired Ambulance spend between 40k-130K ....depending on budget, what they put into it etc ....ive seen some who DONT remove the Emergency lights and i have to remind them being that its Not a working Emergency vehicle or a Parade vehicle Or being owned by a Emergency worker , red /blue lights & the sirens can not be on said vehicles its like a $1200 or more fine even if your not running them ... ( im a retired emergency worker myself ) most Ambulance New cost bout $200,000 or more depending on specs yes some have hydraulics , newer ones are getting stretcher lifts for obese patients so the EMT or paramedic wont kill themself trying to put the stretcher into the ambulance .. those units run bout 400-500,000 new .
