Thanks for the comments. I still plan on the Remco pump. The way depreciation seems to work it will be cost effective to convert the Sienna rather than the 30 to 40K for a new fully equipped van. Besides, we really like the Sienna. Dolly towing was great when I was young, but gets hard on the back and knees with age. The plan is to have hitch/auto shop install the Remco, the baseplate, the light wires, and the ReadyBrake cable. The shop doesn't think I need a hot line to the battery, but the new Allegro Red catalog notes a hot line in the tow plug, so I may add it anyway. I was really just wondering if anyone else was towing the Sienna.
Thank all, Gary
