How big is too big? How small is too small?

I would think this would open opportunity for a wider selection of motor homes to choose from, actually ideal for boat launching regardless of the motor home. This because the axle is real close to the ball. And in most cases with the load on a motor home, the front axle is under-loaded with lots of margin to weigh it with a boat trailer in a boat ramp parking lot. It won't sag much at all.

When considering the dynamics in boat launching, a large rear overhang on the motor home will place the ball way up in the air when backing up to approach the ramp. I wonder with some steeper ramps, the tail of the trailer could make contact or worse.

Too long of a wheel base is another concern. With the rear axle on the ramp and the front axle on flat ground, a long span between them on a steep ramp could get close enough to damage something on the motor home itself.

Look at my signature and picture my rig backing down a boat ramp. My rig has a 158" wheel base and is 23'-8" in over-all length.

So much depends on the boat ramp. If you are traveling around the country with your boat, you will be presented with a flavor of ramp conditions.
