On the last two trips, the RV has been pulling to the right so that I needed to have a constant back presser in the opposite direction. I bought it to Pinky's (local truck tire/alignment shop) for an alignment. What a different driving it home and the Safe-T-Plus works better now too. My point is I should have done this sooner but the misalignment grows over time and you just get used to it until it really bad. Feels like a sports car again. One of the front tires was bad and caused the pull to the right. They swapped it with another one in the back inside and that fitted it so they could set the toe and camber correctly.
$200 but worth it.

Yeah, a good alignment is critical. The Saf-T-Plus can also cause it to pull to one side if it isn't centered properly. I had to adjust my Saf-T-Plus about 4 times before I got it perfect.
On my class C I got an alignment, installed bigger front and rear swaybars (Hellwig), and installed a Saf-T-Plus, and it drives significantly better now. I'll probably also install Bilstein HD shocks at some point.
