I currently have a 2018 Four winds 22E on a ford E350 Chassis (GVWR 12,500)
My Total Weight is 10,900 lbs fully loaded with all tanks full, including Me and 1 passenger.
80 PSI is too much the ride is hard and bouncy, I keep The tires at 70 PSI
You should have your unit weighed.
I am not sure if my spacing is like yours, but most likely is, If I get a chance tomorrow I will look. I am not concerned of the space and have 20,000 miles on it.
