Suggestions for making my F53 a little easier to drive

Well, you are new to Rving, so, look at the front tires for uneven wear. If so have the aliment checked. Check underneath for sway bar end links and bushings for wear. If you do not have a rear track bar, you should get one, as the long springs and large shackle bushings allow the rear end to shift under the MH, causing the MH to be somewhat hard to handle. The front axel is prone to the same problems as the rear, so a front track bar may be needed also. All tire pressures should be close to the same.
