I am on my 3rd travel trailer. I have learned never to leave the RV dealer without swapping out the manual tongue jack for a power jack. Also, just take your time on the delivery inspection, so that you can learn how the various systems work, and also on how to hook up the weight distribution hitch. Also, it sounds minor, but I like my television to be straight across from the seating I will be using to watch TV. After about 5 minutes of having to turn your neck 90 degrees to watch TV, you will know what I mean.
