I see some RVs with extreme overhang at the rear. That could exacerbate any overloading because that's where the extra weight is likely to go.
If you have ever pulled a trailer that was way heavy in the rear then you know how important weight distribution is.
Acceleration shifts the weight even more towards the rear that's why the wobble kicks in.
Depending on the location of the tanks those could play a big part.
BTW, I consider those tires unsafe. Even if they were new, 4 to 5 yrs
puts them near the end and sitting all that time cannot be good.
I would replace them all. Rearrange your weighty items and go somewhere.
Thank you everyone for your impute! Front tires were way out of round according to the shop, rear tires were not as bad but replaced all 7 (spare was blown from another trip) the only problem they said the steering had was 'lots of grease' as I am stupid and don't remove the grease when I do it. Drive home was great until I went to park and the fuel pump air locked... I thought I had fixed that last year (fuel line between the tank and pump had a cut in it) Good to know these things before I leave though! More work to do, again, thank you for the information guys!
Edit: PS, When I went looking for a motorhome I was VERY clear not to have overhang, I go places where that overhang would hit things a lot. 30 foot Alumalite has I think a 3'6" overhang
