I had the same experience with a 99 tacoma. Very weak springs,bad MPG and it was a 4cy stick.I have a 2011 Tundra 5.7 Crewmax....never been so disappointed in a truck I spent well over 40K on. The leather seats are junk and have already been replaced once, the fiberglass bed cover lasted 1 year before it self destructed (removed it from vehicle), it's in the shop now for a broken leaf spring, and the mileage is horrible. I use the truck to commute to work, and carry my sons dirt bike to races. The spring shop said the Tundra has an extremely weak suspension, the springs are being made of junk steel in Mexico. Very sad situation for a "new" automobile.
