I would do all the work myself. I'm a car mechanic on the side so I'm familiar with car engineering just not motor home/camper stuff.
I know it doesn't run because I'm pretty sure a mouse has chewed the wiring harness.
As for the inside I have no idea what works and what does it and I haven't crawled underneath it yet but I can confirm it's the one ton axle.
It's got some issues like a cracked front window some missing aux lights, brakelight busted, roof sags a bit, the air conditioner probably doesn't work.
I'm mainly looking at grabbing this and making it a long-term project to get it roadworthy.
So with a title and non-running condition you would say 500 is fair?
