2007 Toyota Tacoma, V6, crew cab, 4x4 towing a 2017 2109s. Trailer weighs about 4,600 lbs loaded with our gear, but empty fluid tanks. I'm getting about 8.3 mpg and I go about 65-70 mph. It tows pretty good except into the wind or steep hills, then I get passed by big rigs. I'm going to get a newer, bigger truck soon, cuz I don't like being passed by big rigs.
