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

I have been pulling our bass boat for years now with our 26 foot Winniebago Aspect 26a on a Ford E450 v10 platform. It works great in most situations. I have plenty of beef to pull the boat and the MH is fine to drive and park in most places except inner cities. The overhang works great in most ramp sitiuations we have run across. Of course there are some ramps I would not even put my boat in period. You just have to check each one out. We usually already know where we are headed at this point in time so we have cut that issue out. We have not stayed in the MH for months at a time yet so we will see how that part works out in the near future. We have one large slide that really opens up the living space. We love the outdoors so if we had a half a month of rain I am not sure I would stay in the MH the whole time. I would not consider to put a front bumper hitch on our MH since backing up and launching our boat has not been a problem at all. Good luck!
