Wheels
HELP!! We are in the process of buying our first Class A. We currently have a Class C. We do plan to travel a bit. My husband insists we purchase one with the 22 in aluminum wheels. about 1% of the used ones we look at have those. So we are very limited. I would like some experienced advice! Does it really make that much difference having the 22 over the 19.5? We are having quite dilemma over it. Please help make our buying experience more enjoyable!!

We went from 16" to 22.5's and that made a big difference, both in ride and cost to replace! No idea about the difference between 19.5 and 22.5's.

I would be more concerned with the layout that works for you then the size of the wheels.
The larger wheel often means a heavier RV and a higher payload capacity.
Does your husband expect to carry and tow much more then you do with the Class C ? That may be his reasoning.

I'm a fan of 22.5" tires and wouldn't buy an RV with 19".
Reason being the ride and strength of 22" tires.

I would think that the chassis manufacturer would put the right side wheels for their product. If the correct size is 19 going from 19 to 22.5 Might make a clearance problem. There is also a very big price difference between 19 and 22.5. Aluminum is available for either size. They look good and are hard to take care of keeping them looking good. If I were going to go with 19 I would go with steel wheell with good quality wheel covers.

He can always get steel wheels then switch them out to aluminum. In the grand scheme of things it’s really not that much more of an expense.
It would only be the front wheels and out side rears.

I think 22.5 inch wheels ride a lot better than the 19 but, aluminum vs steel with covers is just a matter of aesthetics.

Well,
The first question I might ask is, why does he insist on the 22.5" wheels? Does he just like the looks? Does he associate them with any particular design or coach? If he's using the 22.5" wheel thing as a focal point for a specific design or type of coach, length, etc.? Just because a coach has 22.5" Alloy (Polished Aluminum) wheels, doesn't mean the coach layout is gonna be right for you. And, those wheels, came standard on some coaches while on other coaches of equal value or rank in the lineup, came with steel 22.5 wheels. And that means, if he (and or you) pass up one just because it doesn't have the wheels you'd like, you may be missing out on one that might be just right for you.
Besides, they're not that expensive. If you find a coach with steel wheels and everything else is perfect, you can always buy a set of four, (no need to put an alloy wheel on the inside dual in the rears, most don't) and have EVERYTHING the way you like it.
So, he might have a game plan for wanting the 22.5" Polished Aluminum wheels but, he (and you) need to narrow the playing field a bit and, provide reasoning for the desire, so your hunting efforts will be more concentrated.

Steel to aluminum BTDT, with less unsprung weight they do ride noticeably better

This is from it's first rip after being purchased in lower CA, it was a great first trip at 2200 miles plus. You need to bear in mind it is also my first RV.
Shortly after getting home it got it's aluminum wheels and stripes painted on the slide outs

+1 - OP has to be concerned about the floor plan - not the tire/rim size - leave that to the chassis manufacturer.

Gas - predominantly 19's right? It's been eight years since I went RV shopping, but that's the way I remembered it.
Diesel Pusher - all 22.5s, except maybe the scarce as hens teeth Safari Trek DP.
So I take it you are looking at gas coaches and not finding the bigger rims to be very common.

In the last few years, there's been a number of manufacturers that have produced a "Heavy Duty" gas chassis. And those came/come, with Aluminum 22.5 wheels, along with other heavy duty components.

The Workhorse W24 chassis comes with 22.5 wheels.

The wheel size on Ford F53 gas coaches is determined by the chassis weight rating.
At least for “recent” model years:
The 22k GVWR / 26k GCWR chassis may come on either 19.5” or 22” wheels. The choice is up to the coach builder. In general, the higher end gas coaches on this chassis will have the 22s, while more budget oriented coaches will come on the 19.5s.
All chasiss smaller than the 22/26k come on 19s.
The larger 24/30k and 26/30k chassis’s come only on 22s.
Easy enough.......
And while 22s tend to provide a smoother ride for several reasons, you should also focus on wheelbase to overall length ratio. It can have a major impact on driving characteristics related to rear bias loading (tail wagging the dog / pendulum effect and light twitchy steering due to too much weight too far behind the rear axle, regardles of what the actual weight on the rear axle is) and and rear “sail area” (affecting push / pull tendencies).
Think the shorter the rear overhang the better. 50% wheelbase to length ratio is minimal and barely marginal at best, many fall around 52/53%, 55% is good, and the only one I have calculated to be 57%+ is a Tiffin 31SA. As expected, the higher quality gas coaches tend to have the higher wheelbase to length ratios.
