I used to tow my 20' Seafari with my 2WD Toyota Tacoma Pre-Runner with no problems in many different ramps along the Dade/Broward coast. Many times I had to dunk the trailer to its wheels to get to the boat and not once did I have a problem.
The 2007 Toyota Tundra 2WD also has an electronic "limited slip differential" that works very well in slippery ramps, and the 381 hp/401 lbs torque lets you pull up to 10,600 lbs. At this time they're selling them pretty cheap since the '08's are in so now's the time to upgrade. BTW, mine is giving me about 15 mpg in the city and close to 21 mpg on the highway, not bad for this monster!
