Empty is 10,702. max with tow is 19,050. Diff is 8,348. Even if I towed it's max of 5,000 that still leaves 3,348.
If it was a Chevy chassis, empty would be 10,550. max would be 17,550, Diff is 7,050. max towed would be 3,500 so I'd have 3,550 left.
You still have to worry about each axle weight and there's no way I'd have room for even close to that much weight distributed over each axle but it's there. Some I looked at were well under 2,000 pounds left when pulling something. A few people, gas and water can equal almost that.
The plan was find something under 27' with no slides with a 450 chassis then weight and handling should not be an issue. Did not want to be driving something that was at or near it's max capacity all the time.
