You didn't say the year or model so barring, THIS IS THE ONLY MODEL LEFT ON THS PLANET here goes;
Two weeks time off, driving, expenses, you don't really know if it will make it home without alot of time and money.
If your paying 1,000.00 for this gutted trailer you will be better off buying a fixxer uppper in your area, spending 5 times the money, take it home and spend a weekend gutting it. Make sure it has a good shell.
Then you still have your time off, and I feel certain you will have less money in your trailer, not to mention the stress factor.
Your discription of that trailer and the cross country trip are a recipe for disaster.
