Tires?
Just brought home, new to us, 2014 Tiffin Open Road 36LA. It has the original tires with lots of tread, but bad looking cracked sidewalls. The original tires are Michelins 255/80R 22.5 GXRV. I w...

There are a few considerations with changing tire sizes. It's hard or impossible to say which, if any, of these would cause you trouble without more information (specifically what information should be pretty obvious).
The overall diameter of the new tires is a slightly smaller, which means your speedometer and odometer will read about 1.5% higher than is correct--probably not enough to worry about.
The new tires are a little wider; there are a couple of potential concerns with that. First, if the rims are not wide enough, it may not be safe to use the wider tires with them; however, I highly doubt that would be any concern as it's not a big change in width. Perhaps more likely is that the clearance between the dually tires may become too small, leading to rubbing and/or overly reduced heat dissipation.
Finally, you also need to check the weight handling capacities of the two tires, and ensure the new ones are sufficient (and at pressures that are within the limits of your wheels). I doubt there is a lot of difference there, so you're most likely fine here.
My hunch is that the new size would be perfectly acceptable, but do double-check with someone who really knows what they're doing or talking about (rather than just me). If you happen to have a spare, whether mounted or otherwise, it needs to be the same basic size as the others, of course.
