That is a PERFECT combo. My suggestion to make things easy would be to swap the utility body to the Ranger so the camper will fit more easily. Then you can tow the F550 and trailer behind the Ranger so you can use the F550 as a grocery getter from camp. The F550 should have adequate load carrying capacity to get a full load of chocolate milk if you beef up the suspension well enough. Towing the whole train should be OK as long as you get the 64" titanium torque lift tow system and possibly add some 2x4's to the side to extend from the bumper to the sides of the hitch. To even out the weight distribution you should put a snowmobile or quad on the front hitch of the Ranger. What a sweet rig that'll be! But you will probably need a K&N filter for the Ranger to have excess power.
