Tires
I recently blew out a michelin outside rear dually tire on our Cambria 30J. I have 34k on the 5+ year old tires, no cracks and I keep 80 psi in the tires. I thought about replacing the blown tire with...

I concur. We like narrow tires for a multitude of reasons, one being they seem to work better in snow.....which we see a bit. I was just using the assumption that we would see a greater mph change, and the correction would be wise. When we got our rig, it had already been computer chipped....and while I haven’t actually checked, I figured that the tire size was reprogramable. If not needed.....all the better! The only bad thing, of course “not” spending money is not really a bad thing”.....it had brand new tires when we bought it last August. It will be a while before we get the much needed ground clearance with taller tires. When we win the lottery :B.....it will get a 4x4 conversion, which will cure most any clearance issues, as well as low range for those steep grades and boat removal from slick ramps!
Is your current rig a Class C?
Our 24 foot E450 Class C can still crawl along great with it's 4:56 rear differential, even though I've countered that slightly with the taller tires.
The one thing I don't like about 4X4 conversions is the lifting of the whole rig, thus doing something you don't want - creating a higher overall center of gravity. You want everything as low as possible in a 4X4 for off-highway use - EXCEPT the undercarriage and suspension/drive components. Increasing tire diameters thus does just what you want - raising undercarriage and suspension/drive components for rough roads while at the same time not raising the overall center of gravity any more than absolutely necessary.
We take our Class C into the Oregon and Utah back country with, so far, no problems - but we we do have to travel slow when off-highway with it.
