You are right. It is very long as it is. I am only making it to fit my race car, so it (the bed) will only be 3.7mts long. i have moved it closer to the crane now and am fitting 3 ft bolt on (ford made) chassis extensions to the rear of the chassis, shipping them from the UK soon. Was also looking at making it hydraulic demount type bed.
want it to look like this, pic taken from ebay UK. looks long enough, dont think the chassis has been extended in the middle. maybe someone on here knows who made it?
I decided to put the tray back on, as at the moment i am shortly to be out of work for a bit, and would get more use out of the tray, however i have put on the demountable winch, and second battery system (still to be wired in) i intend moving the tray as far forward as possible and making it into a hydraulic tipper as well, as lifting it loaded with the crane is just not safe.
