Pulling the BRP RT-622 Trailer with an RT can't be beat
I'll openly admit that I miss our RT-622 trailer from BRP. As others have stated, that thing pulls like a dream. On our trip back in 2010 to Florida, we got caught going through the moutains in GA in a heavy downpour, at 80 mph, and even in the heavy rain, you could hardly tell it was back there. BRP did a great job when designing the RT & the trailer.
I wanted something Teddy & I could sleep in tho, so that's why we got the Moto-Mate camper that we have now. It doesn't handle nearly as well as the BRP trailer, but in all fairness, it is roughly the SAME SIZE AS THE SPYDER, so I knew going in that it wouldn't handle as well. With its size, proper loading makes a huge difference. To much weight forward, & you can get a "fish-tailing" effect on the rear of the Spyder. To much weight to the rear of the trailer & you can get a bouncing effect on the rear of the Spyder. Once I learned 50/50 down the center, its now much more smooth of a ryde. Once, on a group ryde (I wont say when, where or who) while trying to keep up with the leader, we got to tripple digits while pulling the Moto-Mate camper & it handeled it very well.
With the BRP trailer, you will likely loose about 2- 4 MPGs. With our Moto-Mate, its closer to 4-6 MPGs. Either way you go, the Spyder RT is made to tow.
