Kaiser Jeep M725 ambulance

M-725 Kaiser Jeep Ambulance. Pros: re-engined with Chevy 350SB V-8 and transmission adapter to original transmission. New brakes and tires. All lights, siren, spot light working. 2 new batteries. Cons: vehicle was running when put up in the fall. It has an electrical issue that will cause the batteries to discharge (ground problem or short? I'm a med tech- not an electrical engineer/vehicle mechanic). Needs a new gas tank and filler tube (gas tank has pin holes I've been told.) Missing the 4 ceiling footman loops but have the new old stock litter straps and litter securing straps for floor. 2 litters, litter IV bag hanger, pneumatic splint set included. Has the correct rifle racks installed in the crew compartment. 4 wheel drive is working.
I wanted to put the vehicle in parades and use at our NP for veterans to play with but we need to free up the funds for other projects. Please contact me with any questions.
