Cash in person is always best. Have an adventure in your rig !
You won't be lacking for power. I had a F350 Pickup, 7.3, it would tow and never seem stressed. It got 16 mpg, Loaded, empty ,towing, 16 mpg.
It was a 2WD. It got stuck if it even looked at mud.

My experience with a new 30 foot V-10 motorhome bought in 1999. 7-8.5 mpg. Depreciation over 7 years 30,000 miles $30,000. Other costs were tires and insurance. I got it stuck a couple of times a few feet off road, so 0 off road capability.
My family had some great trips and it was worth every...
I always find it funny that people ask for help, "What else should I do to get this thing mechanically up to date? ", but don't want to share something useful like what the market value might be.
