Clients ambulance build is coming alone! A lot of demo had to be done. Rear box has low ceilings so the new ceiling needed to be done in sheets of aluminum so ceiling height wasn’t reduced. Nicely insulated, eight 12v puck lights, two exhaust fans, speakers, and a 48v air conditioner, all incorporated into the ceiling. Time to start building the electrical system to get all this stuff powered up!

This is probably the most advanced electrical system we’ve ever had the privilege of building. It will souly rely on the batteries to power everything it is 40 foot monster of a bus!

We here at JM Custom Coach Builders have been working o this ambulance for 6 years and we can finally say it’s done! We worked late into the evening to finish this wrap job to get her ready for pride this weekend! We are starting a sister company called JM mobile Entertainment. You will be able to rent this beauty for events, complete with a dj on the roof! Come visit us in Asbury park this weekend! I we’ll be parked in the lot next to the Stone pony with some DJs on the roof! Sunday we’ll be riding this thing through the pride parade! Hope to see you!

I want to thank Bren Marra from Agx Designs for creating this beautiful wrap job and getting it done in time!

We got a client that built his van out himself but needed us to put in a full electrical system for this sprinter van. System comes complete with roof top AC with heat pump, rooftop fan, overhead lighting, full sound system tied into an on board TV, 300ah lithium battery, and a 60A DC to DC charger. Enjoy the summer Rob!
