It is a 39N, so it has an air suspension. I would check the airbags on the suspension, see if they are actually airing up. An easy way to tell is, let the air out, after the air is out, measure the wheel wheels all the way around, ground to the top of the wheel well lip. Then air them up, and remeasure, you should see a few inches difference. There should also be a sticker from Fleetwood behind the drivers seat on the wall. Look for the psi on it for the front tires, your fronts seem high, should be around 95-105.
EDIT: Added what to measure, I goofed it up the first time :o
