I'm having a lazy Saturday today so forgive me if I'm factually imbalanced or wrong....... someone posted on here (or was it another forum?) a long while ago about chasing the aerodynamics tail needlessly with our teardrops. Essentially the trailer is following behind the TV, in 'dirty'' air, not the smoother air the TV is originally breaking. If the teardrop was in front of the TV, that's a different story, therefore the aerodynamics argument point of the teardrop, is moot. Dont get me wrong though the teardrop or aerodynamic shapes we use are dead COOL looking, generally pleasing to the eye of the beholder, with our individual practicalities of use added in. '
For my builds any shape better than a brick outhouse is okay

In addition, from previous posters above: A four inch mattress is too thin UNLESS you invest in a darned good one.
33 inch cabin height space is really impractical once you've been out a few times. Go for a 48'' and give over to some real breathing space
