Im gogin to be hauling a 28 foot enclosed trailer adn a race car bye my dodge ram cummins. do i need to go with the OD on or off?

 

what kinda terrian are you goin gto be in man? i pull in OD all day long unless i drop below 50 then i turn it off pulling grades. but even some grades i can pull strong in OD and my temps dont rise.

go by the gague and it the speed is dropping then drop a gear.

if fluid gets hot drop a gear. etc.....

Most Ive towed with my 93 was a 1800lb camper and a 6k horse setup. ran Od most of the way with good temps. I have both coolers though. youll know when its strugglin. your better off to wind it up a little ,instead of luggin it to much.

 

I now tow about 11,000# and use OD all the time unless the speed drops below 60 mph, when I switch it out of OD. Been doing this for the last 20,000 miles, and for the 20,000 miles before that, I did the same with an 8,000# trailer. As mentioned previously, if it's a long hill, I also change out of OD if the tranny temps rise above 235F. I change the tranny oil every 10,000-12,000 miles. No problem so far.

ill mostly be goign around town. about 55 to 60 out of town and abuot 40 in town.

 

I disable my OD when im in town under 50. wasted shifting and wear. IMO.

 

below 50 and no sight of going faster O/D stays off id rather wind it up and its easyer on the brakes as well.
