Toad's maiden voyage is complete. Everything works as planned and we hardly know its there, although I am sure we will feel it on our trip through the rookies this June. I think that having the car back there actually reduces the imposed fishtail affect of a passing 18 wheeler.
A drop hitch was not needed even though our 2552 is four wheel drive and sits much higher than the standard rear wheel drive. The tow bar is only 3/4" out of level, well within spec. The Rock Tamers go on like a dream, are easily removed and look like they will provide good protection for the front of our Envision.
We use two rear cameras, one pointed down at the hitch and toad the other aimed farther back to look at traffic. Two viewing screens as well, one on Pioneer radio and the other on our Garmin GPS. Both give us the ability to closely monitor how things are going back there.
Added a few pictures, hooked up and not. - Dick and Chris
