The weight police are really going to get me. I tow our Grand Cherokee on the car hauler,in my Avatar,with our Newmar gasser(362 HP V 10). I did trailer tow testing for AMC Jeep,and I know how vehicles are rated. Chrysler,at one time rented prototype trucks to Jayco, to get in service data. Trucks rated at 14000# tow, were regularly towing 21000# all across the USA.
2008 Newmar Canyon Star - 2007 Dodge Dakota Toad - Ready Brute tow bar & brake system - one cat - Sassy 14
All the advice is greatly appreciated; i did go ahead and have a towbar plate installed on the cherokee and towed it 2200 miles to western virgina. Definitely not a "don't know it's back there" situation but
rv performed well and handled the load ok. Used to pull a HHR, this felt like there were two HHR's back there.
I tow an '02 GC behind my b230 Cummings pusher and frankly, I wish I had chosen a different toad--I think the GC is just too heavy for my unit. Love the Cherokee for it's bullet proof nature and its comfort but we find that we just don't need the size or the poor MPG of the Jeep when we travel. I use a Ready Brute braking system and it certainly handles the toad well but it is a massive tow bar system.
The difference in RPM for my MH between flat towing the GC at 60MPH and when not attached (and I just checked this) is 250RPM--about 1700 without the toad and just at 200RPM with it. Have no idea what fuel mileage difference this makes.
I tow an Explorer Sport Trac behind our W22. Weight as towed is about 4850-4900. I've upgraded everything in the system except the original tow hitch (5K capacity) to a minimum of 10,000 lbs equipment. So far, towed over 11K miles with no problems and no wear/tear on the hitch in evidence. I use an Even Brake, and with the 4 wheel disc brakes on the Sport Trac, it usually slows the motorhome pretty rapidly.
