Andy, thank you very much for trying to be of service to our membership. I cannot reveal details but we have three members who list both a Nissan Armada and a 28' International. One of them checked in earlier this month. This report of yours may not see relevant eyes right away. I'd hope somebody recognizes this as their set-up at some time.
Do you have any sample photos of similar setups that need improvement?
Would you agree that one can tell a lot by standing well back on a level surface and observing that both the TV & trailer are parallel to the ground?
The more pointers the better...
Please keep it up! Karma your way.
