Hey Gregory! I checked with our vendors and the best suspension upgrade I could find for your 2014 Thor ACE 29.3 are going to be a set of SumoSprings for both the front and rear axles. Sumosprings are two piece springs that act independently of each other to help with body roll. They give you the same support as air bags but do not require the maintenance or require you to adjust the air pressure. Additionally, these will work well with any leveling system you have installed unlike airbags. I have listed the parts you will need below:
Front Axle - SumoSprings Rebel Custom Helper Springs item # SSF-170-40-2
Rear Axle - SumoSprings Maxim Custom Helper Springs item # SSR-187-40-1
I have linked a couple of review videos below so you can see how these springs get installed and see their functions demonstrated.
