Re: Towing 10,000 lbs. with Infinity QX56
The vehicle will maybe do it, however:
1. There may be a law in your state re: overloading.
2. As stated above, insurance company problems
3. If theres a warranty left on that vehicle, and they find out, you have no warranty any more.
With whatever you buy for a boat, hopefully within the tow rating, make sure the trailer has brakes on both axles if 2 axle, and 2 of the 3 on a 3 axle, and Preferrably, disk brakes. Don't know about where you live and boat, buy Florida required this (state statute).
Nextly, radial tires smooth out the ride. Mine has them, and I have about 3K miles on them. They show no wear, so far.
Aluminum trailers weigh about 40% less than steel. Might save 1000# of tow weight here.
