I've been pulling this 6 X 12 with a Tahoe for the last several years. One foot extra tall, side door.
However, friends and I will share the trailer, go to the same event and we disassemble and pad-pack the planes to fit more. This helps reduce the pain of the horrible gas mileage I get (Tahoe drops from 16 mpg freeway to 9 mpg pulling the trailer!). I don't know if the V-front would help with mpg. Doesn't sound like it listening to jonkoppisch.

Curious, was that picture with the dog taken at the Newton SkyKings field. Dog looks like the famous old "MOON" dog! If so, he has been gone for several years now and was replaced by the pop and water bottle chewing "Orion".
Not sure if your trailer is the same size as my 6 x 12 or not. I can easily stand up in mine when the shelf is removed. I have a single shelf at about the half height level and it is fixed. It is notched in the front ... only half width from the rear of the door forward which makes loading easier. Everything gets tied down or is well padded with moving blankets of foam padding if not tied. I once saw a load of airplanes that were not tied down after it went down several miles of bad road. I learned from that scene the importance of securing everything.
I've pulled my trailer with a Silverado PU and now a GMC Sierra ... both had toppers. Mileage drops about 5-6 MPG with the trailer at highway speeds .... usually 75 mph. The GMC still gets about 13-14 MPG which isn't too bad considering the number of airplanes and equipment that can be hauled. I've always thought a V front trailer would pull easier but for what it would cost me to trade trailers, I can buy a whole lot of gas!
