20 inch vs 22 inch rims - any difference to towing?

Nope. My F250 came stock with 20s. In fact most HD trucks above the most basic trim levels will have 20s.

A 22, with same overall diameter as the 20, would have less sidewall which translates to less ride comfort but better handling due to the reduced tire squirm side-to-side. Verify the load carrying capacity, of course.

I'd prefer to tow with 20's over 22's myself but you could do a 305/45r22 Nitto Terra Grappler G2 and not lose any load rating. We put simple leveling kits (2" Ready lift) which enables you to do a 20x9, offset around a +18 with a 33x12.50/20 ( Nitto, Toyo, Mickey Thonpson....). In 22's the same but most 22's will be 22x9.5, look at Fuel wheels, XD, Moto Metal....in these sizes the 22's will ride just as good as the 20's and the wheel and tire selection very similar. With the mild 2" leveling kit you can run a 285/50r22E Terra G2. Your good either way, good luck!

If you stick with the same overall tire diameter, meaning you'd have to go with a lower profile sidewall, you won't see any degradation in performace but the ride will be harsher. If you upsize tire diameter you will see a loss in performance as you are effectively changing the gear ratio.

With 22s you will also be much more limited in tire selection and they will cost more.
