Still on the fence here, also about v6 vs v8 and if the tow package is crucial for these particular vehicles or if I can add a transmission cooler and call it good.
4th Gen 4Runner (03-09) -- Both V6 and V8 have a trans cooler housed inside the radiator. V8 model also has a small external trans cooler on front of radiator. I changed out OEM trans cooler on my V8 and installed a larger one, but I was towing much heavier than you, plus a full size travel trailer, so wind resistance was like pulling a barn door down the hiway. Plus I live in the extreme summer heat of AZ desert. So OEM cooling system may be quite adequate for your usage. I never overheated, just took precautions.
There is an excellent active 4Runner forum, T4R.org. There are many members there with 200K to 500K on the clock, and many towing. Very very reliable vehicles. Both the V6 and V8 in those vehicles are very good engines.
