I've been driving, for work and for fun, a '96 T-100 for the past 13 years. Am now considering getting a Tacoma. It will be almost exclusively for carrying my pop-up slide-in camper. I have an All Terrain Camper, Bobcat model. It weighs 700lbs dry, probably around 1000 lbs loaded with gear, etc. I am planning to build a similar camper and hope to lower the weight by 200-300 lbs. I am wondering if a 2.7 access cab with 4x4 is sufficient to carrying this weight without being too much of a strain on the engine. The camper is low profile, the over-the-cab part is only 8" high in the lowered, travelling position. My T-100 doesn't mind a bit but it is the 6 cylinder. I am retired(yeah) and plan to spend a great deal of time on the road, but seldom on a paved road. I want to get something that will give me the best possible gas mileage. I don't need to drive fast and I don't get TOO crazy with the off road stuff. I don't want to over work my truck and shorten it's life though. I have 376,000 miles on the T-100 and I hope to get that much out of my Tacoma. 2.7 or should I go with the 6 banger?
