BBBAir,
The bottom box is 4'x8'x2'.....the lid is 4'x8'x6"..........there is no gate in the back. I wanted it to be waterproof and light a gate in the back would be hard to seal and add unessary weight even my 30% plane only weighs 17lbs...not a big deal to lift out.I have pulled it in the rain and it didn't leak a drop..I have also left it out in the sun 100deg and with the air intake, solar powered exhaust fan, and high gloss finish is was cooler inside that out and did not losten monocoat.
