AntonB, I think the idea behind the 80% reserve if for steep hills (I may be wrong). With my setup I'm basically at 80% and haven't encountered an incline I had to slow down for. It will downshift and run at 4000 RPMs on the bigger climbs though, but it still maintains 60 MPH (my usual towing speed). I doubt I would be able to maintain that speed if I was at max tow though. If you find it struggling you may be able to change the rear end gearing which is less $ than buying a new tow vehicle.
