Hope your first trip was fun anyway. I too learned the hard way on our first trips. What we forgot I did the same as you, when we got home we put it in the the TT. If we only had one and needed it at home we put it on a list of things to buy for the TT. On one of our trips a cabinet door came open. When we arrived at the camp ground and opened the slide it caught the cabinet door and broke it. After posting on FRF I received several suggestions to keep this from happening again. A trip to Home Depot and some spring loaded hinges should prevent future problems. I also took the advice of putting velcro straps through the handles. Now I just have to remember to use them.
A list is a good idea
