Ok I have a 2001 SCREW with a 4.6 in it.
I have the oil cooler and the trans cooler and I want to tow a 7x14 enclosed trailer with a couple quads in the back.
Is there anything that I need to do to make sure I dont overwork the rig?

 

you are set up good. get a transmission flush and replace ATF fluid with synthetics, you might look at getting a shift kit installed in the tranny.

 

You should be fine. I have an 03 4.2 and haul two quads all the time one a 6x12 trailer. Not enclosed though

 

I've got a 98 4.6 with 277xxx miles and it will still haul or tow a lot. you will be fine pulling the trailer. remember, your driving a Ford lol you will be fine

 

How often are you going to be towing? If it will be regularly, look at getting a shift kit. If it will only be once or twice, you should be good to go. Just make sure all of your fluids are good and tires aired up.

I don't know how often you tow but when you hook up, cross the safety chains to the trailer. Have the one from the left hook to the right side of the truck and vise versa.

 

Standard towing safety If your coupler fails, the crossed chains catch it and keep it from gouging into the pavement and causing an abrupt stop and/or flip.
