From Dec. 2000 to Dec 2004 I towed my 18.5ft Yarcraft boat/with trailer behind my 3280RL Montana fifth wheel. Towed with Dodge 2500 Cummins from Baja Sur, Mexico to Lac La Ronge, Saskatchewan.. and back...each year.
I had the boat hitch welded to the Montana's frame by an expert machine shop. Never had a problem with the weight or any swaying.
Some states do not allow this type of towing. Minnesota does not!
Minnesota DOES allow double towing however the rig in your picture would be well over the length limit. So I guess your last statement is true for your rig.
My wife and i also double tow our rig, were in manitoba canada. Havent double towed with this camper yet, i am just about to fab up and reiforce the frame to be more than capable to tow our 1850 crestliner, about 3500ish lbs. Camper has an IBEAM frame at the back theirs two 12" sections of 2 x 4 x 3/16" structural tubing welded to the ibeam frame which holds the rear bumper onto the camper. I believe ill utilize the existing 2x4 tubing and build off of that, itll make the reciver at the perfect height. Overall when were all hooked up well be roughly 68-69 feet. Legal length in manitoba is 71ft. All in all i think theirs more misconception about double towing like this, the boat shadows the camper quite nicely, just have to learn how to take corners just a little wider!
Mile high,looks good to me. We towed double/triple for 18 years with our little Eagle 215 SD and never had a problem. By the way, I was, and am, not good enough to back the boat down the ramp with the trailer attached. I don't think that Mile High does that either. Towed boats ranging from about 2,500 to 5,000 pounds behind that little trailer.
"It is heavy for a double tow, but just right for a triple tow!"
Truck (tow vehicle), trailer, trailer...
Sure looks like a double tow to me.
But, if you want to call it a "triple tow", go for it!
Just don't get snarly when somebody asks you if towing three trailers is REALLY legal.
It will happen sooner or later...
