.... and a 1/2 tank of fuel.
Mike --- I have towed 2 to 3 cords of wood and according to the season (wet wood or dried out a bit) the weight varies with time.
I am very sure that it is well over 6-7,000 lbs for the wood alone, plus the trailer adding another 1,000 lbs .... and have had no troubles with doing it almost every year.
Add in a couple of buddies (I can only lift 15lbs and if I have to exceed that limit, I have to remove the appropriate amount of clothing to compensate) so they do all the grunt stuff. Don't worry --- I feed them well.
Chainsaws, fuel, a survival pack (150lbs at least) and down the road we go --- safely and I feel with very good control.
Of course, I use electric b rakes because surge brakes are really not very good and they grab - or fail to grab -- and they are really miserable to back up with as they will apply unless you jump out of the seat and put the lockout pin (usually missing-lost on U-Haul stuff) in the actuator every time you need to go in reverse. A Royal pain in the a$$ if you ask me.
WARNING --- most chimpanzee/ex-burger-flippers working at U-Haul, cannot figure out the stock lighting on your TB and they can certainly screw it up by tapping into wires and bulbs with their limited intelligence.
I would never allow anyone by ME to add trailer wiring to my vehicle because the trailer lights have NOTHING TO DO WITH THE ACTUAL TAILLIGHTS OR BRAKE LIGHTS!
They are a seperate circuit alltogether!
A big problem is that GM didn't comply with the RVIAA standards for trailer electrical wiring --- I think they went with the:
The Royal Canadian 'Electricity Is Ethereal; Is Omnipotetent' Wiring Society
standards ... or better known as ---> 'EIEIO' standard.
Sadly, you cannot convert the RV (hah-ha!) connector on the back of your TB (a pox on GM engineers for this) to the RVIAA wiring positions and you will need to either replace the car-side connex with a real trailer wiring receptical or find some sortta convertor.
The GM Pins vary in size (of course they do!) and current carrying capacity (natch!) and if you tried for a conversion, positionally, all the grounds woiuld go through the smallest connector on the vehicle-side ... and that's a no-no.
On the convertor --- I don't think such a thing exists --- not as far south from Canada as I am anyway.
Oh yeah --- ya gotta connect the red mystery wire - under the hood, driver's side, next to the fuse/relay box.
I'll be back after Physical Therapy ....
