366
Rabbit,
I had a 1992 GMC Toter,with a 366.Did you CATCH that(HAD)it pulled on Flat ground FINE.and would pull my 50' no problem.
BUT,1st of all.
The motor is turning 4k @ 68mph,because it has too to make the Rig go down the Road!
That part SCARED tha Hell out of me,although I know guys that Work for U-Haul and say you can drop a Brick on the Throttle and they will Run until the Tanks are Dry!And,by the way,that dont take long either?About 5-6 MPG.
IF you dont have ANY Hills,or they are short,OK.If your in Hill countrty?NO WAY!
GooD-Luck,..............?
