Just looked at my owners book for weights and limits. Mine's a 1998 26' on an E450 superduty ford chassis. Max tow weight is 3500lbs with a max tongue weight of 300 lbs. Combined gross vehicle weight is 20,000 lbs with max vehicle weight of 14500lbs. In comparison, my E350 passenger van is rated for a 10,000 lb trailer with 1000 lb tongue weight. Both vehicles have the same engine ford gas v-10 (although the mh has the banks power pack system)
The van didn't have a problem pulling a 9000lb travel trailer over the mountains.
Not sure I'd want to try and launch a boat with the mh. depending on the steepness of the boat ramp, you might have half the back end stuck in the water before you can get the boat to float. Or unless you're really good, trying to back an empty trailer straight down the ramp when you can't see it. Front hitch might work if you have enough room on the ramp to turn around.
