Hello all. I'd appreciate any feedback that you could give me. I just bought my first vehicle, a Dodge Sport Dakota, std. cab and std. bed. It came with only of those large tool boxes that mount right behind your rear window up on the sides of the bed.

I have a Hangar 9 Edge 540 that I like to fly, but I wanna start taking my pickup. The wings will fit underneath the toolbox with the tailgate closed, but the fuselage is another story. The tailgate has to be open and I can use straps with the hooks to wrap around the landing gear to keep the fuselage from sliding out. However, there's nothing to prevent my 55 lb flight box, and wings from sliding out. How do you guys do this? Please advise. Thanks.
Clint
