We're towing our second Toyota RAV4 automatic 4WD four down. I installed the same Remco pump on our 2011 that I had on our 2002. The 2002 was towed about 30,000 miles, and the 2011 now has about 10,000 miles in tow on it, all with zero problems with the pump. Other than the usual hook up procedures for the tow bar, safety cables, and electrical plug-ins, the only thing we do inside is put it in neutral and leave the key in the "Accessory" position to unlock the steering wheel. Because we also use an electric vacuum pump for the brake system, I do have a towed charge line installed from the coach, so the RAV battery is always kept charged.
