Pretty hard to answer that. Sounds like a personal choice.I have a 2019 4Runner that we tow our camper with, the 4Runner is about a 1000 pounds lighter than my 80. My question is I can get a 2018 5.3 with 6l80e trans that has 100 more ft lbs of torque than my 4Runner if I install it in my 80 I wonder how it would compare to the 4Runner towing? Should I hold out for a 6.0 or 6.2?
