I like my Crewmax, plenty of room for the family and does everything I need it to. Has no problem at all pulling my 26' trailer tha weighs in just a little over 6,000 lbs loaded. I propbably wouldnt like it though if I pulled a 30' 8,500 lb trailer. I get 15 mph around town and 9-10 towing here in the mountains of Utah. I just took it to KY and back (sans trailer) and averaged 17.5 for the 3,700 miles.
I did however pull with my step sons Chevy 2500 diesel and it would easily blow the tundra away. Of course he's a 20 year old punk with a fancy tuner that puts out around 900 HP, so it's not really a fair comparison.
