When checking an RV be sure to spend some time with the doors both inside and out. Here are some helpful hints. Open and close doors to check for solid latch. Look at doors for tight fit at all corners. Place a piece of paper at a corner, close door and pull paper to check for tight seal. Look at seals to check for deterioration or severe compression. Look at the latches on all the cabinet doors. Make sure they all work. Nothing like having dishes, pots and pans and groceries flying when you turn a corner and the door pops open.
