Repair manual? Guide? Etc?

[TexasKeystoner]

I've searched online, and I can't seem to find a schematic owners manual for a 2005 Keystone Montana 2395RK.

My parents used to pull it, and it needs some work before I think it'll sell.

It sat in a storage facility for about 3 years, and someone stole the water heater out of it. There's a random Romex wire hanging under it, and it needs some cosmetic things.

I estimated around $1500 in parts. I have it listed locally for $7000.

Any help would be appreciated.
