I have a 2011 Tacoma and fully equipped Fleet and am really happy with it. My mixed mileage runs right at 15-16 with camper and 21-23 without. I do a lot of forrest service roads and mild off road and need the turning radius of this truck to get to a couple of places I like to go. If you go this route it is worthwhile to upgrade to airbags and/or springs as the Tacoma springs are made for comfort not load carrying, E rated tires and upgraded shocks. I don’t have a problem with breaking with the camper on, but it is easy to increase breaking by going to ARB slotted rotors and green pads, or even more breaking with a big break kit or cheaply with Tundra brakes. My gearing works fine with camper but gearing has changed on the newer Tacomas and quite a few people are re-gearing those even without hauling a camper. The weight on my truck and camper loaded is right at 300 lbs over weight and I am fairly minimalist. If you like to camp with 10 gal of extra gas, full water, custom bumpers and winch, a chain saw and dual batteries you might want to rethink a Tacoma because the weight adds up a lot faster than one would think.
