things to consider that aren't weight
I tow my C-22 Mark 2 on a single axle Trail-Rite trailer behind a 10 year old Pathfinder with a 150 hp V6 and a standard transmission. The vehicle is rated for 3500 lbs and with trailer and some stuff in the boat, this is likely the true weight.For towing, consider these other factors:1. Tyre inflation on the trailer and vehicle: pump it up: flexing biasply sidewalls on the trailer and rolling resistance on the tow unit suck up alot of energy and will take out a bearing: a hot trailer tyre heats the rim which cooks the bearing. Surprising how many people blame a bad bearing or not enough grease when it's under inflation. 55psi and no less.2. Tongue weight: If a 200 lb man can bounce on the swimladder and just get the trailer hitch to lift off the pavement, it's loaded right for front to back.3. Side to side: the trailer will whip if your load favors one tyre over the other, balance it or at least put the heavy stuff on the centreline.4. Transmission: automatics are way better than standards for creeping in traffic or haulouts, but don't even think about it unless you know for sure that you have a transmission cooler on it. You'll cook it on the first long hill.I have trailered 12 hour days in heat and also thru the Rockies, no problem. Behave, remember the brakes on the tow unit are working double time so don't get rammy. I don't know if your tow vehicle is built on a truck or a car chassis, but if GM says it will tow 3500 I would not be concerned.
