There is bountiful advice on tire pressure settings out there, but simple saying 'set to xx PSI' is not optimal. As a matter of safety, a best practice is to be aware of the weight of the MH, ensure a balanced distribution, and maintain tires at the optimum pressure for the load. While this gives you the best defense against tire damage due to under or over inflation, it also happens to make for a better ride and control too.
Start with a proper weigh in. Ideally, each wheel, but if not, at least by front and rear axles. Use this information to confirm a reasonable balance front-to-rear. You are aiming for 1/3 of the weight on the front axle, and 2/3 on the rear (assuming a 2-axle set up with dual rims at the rear - typical of Ford F53 MH chassis and all Jayco Alantes and Precepts).
With the weight per tire data know, you then look up the recommended tire pressure for that load. That should be your cold tire pressure. Adjust as needed.
This brochure explains the process in more detail and provides example calculations:

A couple anecdotes from our experience:
1) when we took the delivery test drive, the steering needed to be realigned. The dealer then had that realigned before we would accept delivery.
2) Once we took delivery of the new MH, we later found that the tires where not checked. We drove hundreds of miles with tires inflated to as low as 52 and as high as 110! Lesson learned: Never assume the tires are properly inflated. Always check, especially before a trip.
3) We stopped at a tire shop and they inflated all the tires to 100psi. That improved stability a bit, the the ride was a bit harsh.
4) Upon weighing and calculating the proper loading, we derived the proper pressure is about 81 psi. Coincidentally, that is very close to what was on the tire pressure label near the driver seat. Lesson here: start with the factory recommendation.
5) Checking pressure before every trip with a gauge is a hassle, but necessary. So, one of the first mods to our new MH was a TPMS. Worth every penny! Not only does it speed up the start up routine, but it offers confidence while underway that all is healthy with the tires. Our system reads both pressure and temperature, and will alarm if either exceed defined thresholds.
So back to the original question of what mods to get for ride . . . start with getting what you have tuned optimally.
- be sure the front suspension is properly aligned
- set the tires for proper pressure based on actual weight
- get a TPMS and a manual tire pressure gauge
Do these before adding mods like steering stabilizers, shocks, etc. You may find that the JayRide is perfectly satisfactory.
Happy motoring!
