First as someone said Get it weighted and inflate tires per load. may be different wheel to wheel. 2nd alignment
Now.. there are 3 issues with many Motor homes.
SWAY Not normally an issue with Workhorse this is side to side Swaying or Rocking. like fans at a rock concert holding up their BIC's during "We are the world".
An improved sway bar can help but WORKHORSE did not skimp on the sway bars.
WAG.. LEAF SPRING suspension (Which workhorse has on all 4 corners) allows the body to move side to side over the axle.. Now if one end moves right and the other left you THINK you are drifting so you compensate.. Then the ends swap and you now think you are drifting the other way and compensate and.. Well .. It is very tiring.
TRAC BARS. also known as PAN HARD bars.. Stop this dead in its tracks. 100% effective if you put on two of 'em one front one rear. (I just did front)
Finally steering stablizers like the Blue Ox Tru-Center (Which I have) or the Safe-T-Steer (which did not offer a "Remote recenter" option when I got my Blue OX.. that option I recommend) help to keep you "on the straight and narrow" as it were. and since your RV is 6" larger than most anything else you may ever drive.. the road is NARROW (The only other vehicle allowed on main roads that wide is a flat bed tow truck and yes.. I drove one once).
Home was where I park it. but alas the.
