truck + 5th wheel RV + glider trailer ??

Double and triple trailering is legal in Utah as long as it is under
the 65 ft, and at least double trailering is legal in Idaho, Arizona,
Wyoming, Nevada and for non-resident rigs, in California (apparently
Ca. residents cannot pull two trailers but I can in their state). I
contacted the DMVs of each of these states to find out if it was legal
and was given the go ahead. I have been hauling my 4 ATVs on a
trailer through these states behind my 5th wheel camping trailer for
50,000 miles during the last 6 years. I have trailer brakes on the
5th wheel but not on the ATV trailer. Since the ATV trailer has a
single axle and weighs less than 750 pounds empty, I do not even need
a license on that trailer. I generally set the cruise control at
70-75mph on those sections of road that allow it but if the road is
rough or windy I'll back off of that. The 5th wheel tows like it is
not even there but the back trailer being a tow behind, is not quite
as stable. The stability of a tow behind trailer is somewhat
dependent on how much tougue weight it has so I put the heavier ATVs
on the front. In order for this arrangement to work very well, the
middle trailer has to be much heavier than the back trailer - just
like the truck or car is much heavier than the trailer it pulls. 5th
wheel trailers, on the other hand can be heavier than the pulling
vehicle and still be stable. I have backed the rig up twice, once to
see if I could do it and once to turn around on a dirt road that I
couldn't get through. I do however, prefer the big parking lots to
turn around in.

I have looked into it as well here in Ontario.
75 feet is legal here. In New York State it is not.
Ontario registered rigs can transit through NY State and other States.
