Wheel cut is a minor point (pro or con) when shopping for a motorhome, but only of academic interest once you own it. You can't change it, so all you can do is learn how to work with the turning radius of what you have. The combination of wheel cut and wheelbase largely determines the turning radius (a tag axle has a small effect also). In a few coaches the size of the front wheel & tires well may limit the wheel cut to less than what the axle can do (the tire hits the well in a tight turn). This is a primary concern if increasing tire diameter or width.
Our coach has a 57 degree wheel cut (ZF IFS front axle on a Freightliner chassis) and 268" wheelbase. It actually turns tighter than the previous coach, which was a Workhorse chassis with 48 degree wheel cut and 228" wheelbase.
