i think it would be in your best intrest to try and find one used. or a rolling frame. i have a 6x12 that i bought just the frame. I put on my own lights, rail, and decking on it witha few other odds and ends. i an tell you right now i dont know how you could fit 6 quads on it unless some were mini quads. I can fit 3 full size quads turned sideways on my trailer.
