T/Gate issues aside........ as "Scott O" points out, be very careful opening the front roof while attached to the TV. The roof can come up very fast on some TM's and you can get slammed up against the rear of the TV if you aren't used to it.
We often open up to have a meal, while on the road. The 1st few times that I did it, I was quite shocked. There is very little room for you to exert any leverage against the roof as it comes at you. I could see a person getting hurt.
