New Motorhome - Front End Alignment

I didn't realize you were having handling problems with your Winnie. Mine has been fine at any speed, without having to do any add ons or mods. Did you ever go lower than the 70 psi you were running in the front tires ? I run 60-65# which is more than enough for the 4,120# on the front axle. I am going to get an alignment (its first in over two years of ownership) because I noticed the outside edge of the right front tire is showing a little extra wear.
Just yesterday, my son showed/told me what to do if/when my one slide, decides not to retract someday.
