Over this past year and after traversing through those large storms on I 10 all the way from FL to TX I feel the need to improve the ride quality and lesson driver fatigue.
Driving during nice weather still requires lots of steering correcting.
I have a solid front axle and understand the ride is compromised slightly as such.
Strong crosswinds will cause a fair amount of correction...no matter what. But in nice weather and with that tag axle, excessive correcting should not be a problem.
Easy stuff first: First, I'd verify correct tire pressure for the weight of the coach(4 corner, preferred). Over inflation can cause some 'wandering'. Secondly, before throwing parts at the problem, I'd take it to a good truck facility that specializes in front end repair and alignment. I see you're in Florida and if close to Orlando, Josam Truck Frame and Alignment is the go to place in that area.(no affiliation) It could be that your front end doesn't have enough positive caster that is causing some wandering...or could have some front end component wear.
Anyway, I'd make sure the front end was in good shape before throwing parts at the problem. Josam*407-438-8944* also does 4 corner weighing. Good luck.
