Wondering if my 2026 4Runner (full-time 4WD, non-hybrid) using weight distribution hitch, and with 700 lbs of CCC left (after passengers, gear, etc) can reasonably tow an Elite 1 Platinum Pkg in mountainous terrain, fully loaded with water, propane, food, gear, etc (but staying below GVWR some)? (for instance I-70 from Denver to Grand Junction, or Beartooth Highway US-212 from Yellowstone to Red Lodge, or Trans Canada/Iceflow Hwys from Calgery to Jasper, and the like) By reasonable I mean adequate. Is it sensible, prudent for safety and wise for vehicle longevity?
