A few thoughts
A few random thoughts about towing. Brakes and balance are probably the biggies. Of course, you have to have enough power to make it somewhere, but even big trucks have a long time getting going when loaded heavily.Some say the tow vehicle needs to be heavier than the load, but, again, a big truck can have a tractor of about 15,000 lbs, and a load of 60,000+ regularly, and some are running up and down the road at over 100,000 lbs load. Again, balance and brakes.I drive a dodge diesel 1 ton dually. Rated for 24,000 combined load, licensed at 24,000 lbs, and often haul around 20,000 gross (truck, trailer(s) and load). Drives just great, feels like it is half loaded.Many rv'ers haul trailers that gross, with their tow vehicles, at well over 20,000 lbs. They drive far more than we do pulling boats.Around cental Missouri where I am now the local farmers all buy 3/4 or 1 ton diesels, a goose neck and take off with a large - often 40' - gooseneck trailer with a load of hay or cows, grossing at 30,000 to 40,000. I've never heard of them having a problem.My son showed up one day with his 3/4 ton Dodge diesel hauling a small trackloader I own, probably grossing about 22,000. He didn't even have brakes working on the trailer! Now, that scared me. He was missing half the "brakes and balance" I mentioned.I'm going to try to attach a picture of a trip I made about a year and a half ago from Central Texas to Central Missouri, a 1000 mile jog. I still had a 3/4 ton diesel then. The truck was full, the trailer was full and the boat was full. I was grossing about 21,000. Not a sign of a problem. I went through Arkansas, some of the crookedest roads around.Bottom line is, make sure your rig is balanced right, make sure you have brakes that will handle it and you can probably pull a pretty big boat. Don't over load your tires. One problem we have that the rv guys don't is getting up the boat ramp. Factor that in.If it were me and I wanted to take off with a big load I wasn't sure of, I'd find a big parking lot and try it out. See how it panic stops. Is it going to jackknife? Is it going to sway? Know what it will do before panic time.Oh, I have a friend who hauls boats for a living. He usually rents his trucks. He usually rents an F350 Ford Dually and pulls things like 30 Catalinas, 30 Tartans and sometimes bigger. Never had a problem that I've heard of.Anyway, just my thoughts.
