Hank,
If the wandering is worse when flat towing the toad, I would suggest starting at the back of the MH first. IMO tail-wag is easier to address. I'm not talking about suspension (shocks, helper springs, or air bags).
1) tow bar height. The manual of my Falcon 2 says that the tow bar (at the receiver) should be no more than +/- 3 inches from level at the car. I use a dual hitch with a 4 inch drop for the tow bar to achieve level. See the below pictures.
2) Install a
Quiet Hitch (or equivalent) everywhere you have a hitch pin/hitch lock. My below tow bar pic does not show it but I have 3 of them installed (receiver, tow bar, bike rack).
3 Trac bar on the rear axle of the MH. Some will say install both a trac bar and a rear sway bar. Yes, you can certainly do that but the trac bar is for tail wag.
After doing the rear end, move on to the front end. I would rather have the rear dialed in before doing any front end changes.
Here is a link to the work that I have had done.
