Short has it's advantages.... When I fall I have a lot less distance (think triangle) to gain velocity...
Got some drawings of a similar trailer today - and the head room in the bedroom is 76".... I'm only 65 (and one half!) inches so think about that! I can jump and not hit my head! I could almost put my hands over my head to put a shirt on...
Short has a couple disadvantages --- when I was getting in and out of my buddy Mikes NASCAR this last weekend - you had to go through the window... and my feet wouldn't touch the ground - that made it a little more difficult...
