So my question is those with auto leveling do you use and if so are there much improvement using a king pin stabilizer?
I have and I use a pin stabilizer (adjustable chocks and rear stabilizers) but I don't have a auto leveling system.
Anywayz...I've seen posts and replies to such questions where a trailer owner with the auto leveling system releveled while having some type of stabilizing jacks (JTs) down. His result was bending the pair on the rear beyond use.
If you use your pin stabilizer just be aware what may happen with a auto leveling system if you decide to relevel.
