Hey everyone. Probably a dumb question, but I'm an idiot so don't expect any better!

At any rate, I have a 2000 F150 Lariat with the 5.4L engine 4x4. I am towing a 6x12 U-Haul trailer with furniture and a snowblower in it while also having a riding mower in the bed from Chicago to Kansas City, MO. I am driving with the O/D off, but wasn't sure about using the cruise control. I would love to use it, but now sure if it's safe for the engine or not. Just wanting to get some input from the forum. Any help would be appreciated. Thanks.

 

should work, i don't see why not. all cruise control does is keep a steady speed going

 

As long as you keep the over drive off, you wont have an issue using it.

 

Owners manual doesn't say much about it. I use my cruise in tow/haul mode on the highway. If it was hilly I would not.

 

Cruise will work fine but you'll burn more gas. Any time the truck looses speed for hills and such the cruise will drop a gear and hammer the gas, ive found that I can get my truck to hold gears better while towing when I'm controlling the throttle.

 

On flat ground turn the OD on....

 

I pull a trailer 6 days a wk. and typically don't use my cruise. It will do a lot of downshifting and will kill gas mileage.

 

A key component of towing safely is not irritating other drivers, slowing onhills that the truck has adequate power to pull would be one of those times. Besides, the fuel is cut on the way down, so some of the energy used to get you up the hill is saved on the way down.

I use cruise all the time when I tow. It lets me concentrate on the road, and what's going on, without pissing off all the other drivers by speeding up and slowing down.
On any newer F150 with the tow package, selectshift allows manual selection of whatever gear you want. For me, M5, cruise control at 65 mph, and all is well.

 

Depending on the terrain id say no. For me im constantly adjusting speeds to make sure my torque converter is locked to maintain a decent mpg, and keep TFTs down, whether that means slowing down or accelerating. But x2 on OD on flat surfaces.

 

Thats what passing lanes are for. Other drivers arent paying for the gas in my truck or for the trans rebuild when it overheats so they can go around if its such a bother, I dont really care. Going fast so I dont **** off other drivers isnt and shouldnt be my main focus when Ive got 6500+ pounds hooked to the back of my truck.
