Well I have read alot of the Towing posts, Some helpful some not so much.

So ill be helping my buddy tow a 22" Cabin Cruiser he bought, He says the trailer is in Great shape, Boats Fiber Glass.

The old owned used to tow it with a V8 Dakota (Not sure if Gen2 or 3)
Mines a 05 Club Cab, V6, Auto, 2wd /w Tow Package and Monroe Load-Adjusting Shocks
Not sure what gears I have, Right now I have a work F-150 home so I cant check.

Ill be doing a complete check on the oil, and such before I leave, and will be running Tow/Haul the whole way.

This will be the heaviest and longest thing Ive towed. Normally I tow a 11' (total length) Utility Trailer.

The Hightway has a few hills, 1 that is steep (The On-Ramp is a 1/4 of the way up it)

I have not had the Transmission Fluid flushed or Filter replaced Also have not had the Coolant flushed / replaced, or Differential Fluid Done.
Those were thing on my list to get done, This only came up a day ago.

 

As long as you are not running an e-fan and are still running your clutch fan, you will be fine. Just don't expect to be flying up the hills, lol.

 

I planned to upgrade the a E-Fan then scrapped the idea, so Im still using the Clutch fan.

I figured id be going SLOW up-hill lol

 

You should be alright. Make sure your brakes are not too wasted

 

The Front are about 6 months old, I had the Calipers, Rotors and Pads replaced. The Rear are ok, but should be replaced soon. Ive never had any issues braking towing a few hundred pounds. But this exceeds that by alot. I plan to be very cautious, give lots of room for braking and such.
