Hi everyone.Trailering shopping. Looking for small LQ and I originally wanted 7"6' basically b/c I want lots of headroom to sit in bed as an alternate to sitting on couch (or place to sit if I take a friend) to hang in bed and watch TC, laptop, etc. I can JUST sit in aq 7"3' with my head hitting the top in a seated position.The trailer available locally that I'm considering is 7"3' so I'm considering it - and wondering if I'm going to save gas mileage pulling it without hitting the wind resistance?I have a Dodge Ram 2500 Diesel 2006 5.7 cummings and it gets great mileage to begin with. Not sure if it's really going to make a difference. But if it did - might sway me waiting to order just another few inches.Thanks.

This is an interesting question. However, can't the gooseneck height vary regardless of the height of the horse area? Wouldn't you need to check that separately? (I actually don't know, but from pictures and trailers I've seen, that seems to be the case.)

There is an aerodynamic advantage to a smaller frontal area, but the differences between your two examples, would be so small as to be negligible. As PH mentioned, many other items can affect your mileage, some more so than a trailer height difference.
Buy the trailer that will be the most comfortable for you. Not only will you enjoy it more, but the resale value of a taller trailer exceeds that of a shorter one.

”The things that cause drag are those areas that have an abrupt change in flow,” says Volvo’s Ed Saxman. “The biggest thing is the top of the trailer. We learned that in 1983 when we were the first manufacturer to put a fairing on the truck roof.” “If there’s nothing on the roof of the cab to throw air over the trailer, the air is like hitting a billboard,” says Tom Davis, Mack’s highway product manager. - See more at: http://www.overdriveonline.com/winds-of-change/?pg=2#sthash.XSIgFa7...
