Hello,

I recently picked up a 2015 F250 Super Duty SWR with 6.2L to haul a new toy hauler travel trailer. Trailer GVWR is 10,000 and I will likely load it to maybe 8500LBs.

This truck pulls is great, even up my steep driveway here in east TN.

My question is.... it would be much easier for where I plan to park if I backed the trailer in. But I am reluctant to try that because I do not know if the reverse gears have enough strength to handle towing up a steep 80 foot driveway or if it has enough torque in reverse. Towing forward the truck qas certainly working but did fine.

Is reverse as strong enough for trying backing up my drive?

Thanks

Gary

 

 

The switch to 4L is in the t-case which is before the pinions, so the stress on the pinions, ring gears, driveshafts, and axles doesn't change.

 

Truck will be fine in forward/reverse/ high or low range. This is a super duty designed for this type of work, it's not a nissan datsun

 

Get a front receiver hitch and you could drive it up and have better control.

THIS^^^^^, unless it's a 5'er and then it would be kind of difficult. Had a front hitch on my old '75 for moving boats and trailers around, works great.

You probably have 3.73 gears. I've switched to 4.88's and have the 3.73's sitting in a box. These gears are massive. I can assure you that the 405 ft lbs of torque you have is not going to hurt it, especially since they hold up to diesels pushing over 1000. While putting a hitch on the front would give you the best control, if your backing up an 80 foot driveway, I'm guessing those tow mirrors would come in handy so you can see what you are actually doing. Reverse is a 3.12 ratio, so it's plenty low enough.

 

The 1st generation Super Duty trucks with the 4R100 transmissions had a weakness for towing heavy in reverse up a hill. That would often cause a transmission overheat.

Your vehicle does not have this issue. You may want to put the truck in 4L for better low speed torque, but it isn't mandatory.
