Towing

As you can see below, I'm a GM sort of guy, so I can't speak to either of the mentioned vehicles. Here are a few generalities that we may want to consider:

Longer wheelbase = better

More horsepower/torque = better (think V8)(developing the peak, in both, lower in the RPM range is better)

Factory tow package = better. Will likely come with a OEM hitch, wiring, HD cooling (radiator & transmission) perhaps a bigger alternator (for increased electrical load, etc. It will also likely have a suitable rear gear for towing.

Of the 2 mentioned, I would lean towards the F150. It has been the best selling pickup for years and enjoys a good reputation among it's owners. That many people can't be wrong. (think resale/trade-in)

I had an "old timer", years ago, tell me to buy twice as much towing capacity as you need and you'll do OK. (if you intend to tow 3000lbs, get something rated to tow at least 6000lbs) He is/was a smart man!

We tow with a f150 Eco boost v6, really like it, 21 mpg not towing, 12 to 14 towing the rpod plenty of power 

I would certainly agree that longer wheelbase, more power and more torque are advisable.  But, there are other alternatives to the pick-up.  We started with a Chevy Astro van and after a year decided that we needed more if we were really going to do long distance, long term towing.  We did a lot of research and decided on the Ford Expedition.  It has most of the same characteristics as a Ford F150, but has the enclosed body style we needed.  there are other, larger vehicles that will do the same-Chevrolet, Dodge, Plymouth, GMC all make equivalent models to the Expedition.

I can say that the Expedition EL with factory tow package does a great job of towing,  We have towed the R Pod from NC across country to the west coast, to the Adirondacks and to Florida so far with no problems.

Choose your tow vehicle by doing a lot of research and closely examine your real needs.

All good points have been made, I would also recommend measuring the distance from the rear axle to the receiver opening. This is overhang. Short overhang= better.

Ok, I did more checking and the V6 can do 3500 "when properly equipped".  Usually that means adding a transmission cooler for smaller tow vehicles.  Larger TVs also add oil coolers, larger alternators and sometimes other stuff.  We towed our pod with a Sienna (3500 pound capacity)  for 2 years w/o a problem.  Towed an even-heavier popup with another minivan also rated for 3500 pounds for several years and with the Sienna for 5 years.  There are many others here that tow with 3500 pound rated TVs.  That said, once I knew we would be pulling long-distance and over the Rockies we moved to a Suburban.
