Thanks for the input. I only got the front sway bar. My shop said they don’t install rears. I especially wonder about the addition of the Sumo springs. Our mechanic works on motor homes but only in good weather because their garage is not large enough.
I’ve not yet weighed the rig. Thought I’d be fine at recommended pressure for now. Should do that as soon as the weather clears. We have a cat scale not too far away.
I downloaded a weight chart for Michelin’s. Here are the weight limits for our e350. So it looks like lower pressure in back. 65 in front and maybe 55 in back. Seems really low if door label recommends 68.
