Sunday I only had a couple hours to play (as I had promised to spend time with the hugs and kisses). So while Ronda was at work I got my truck into the shed and started measuring for tray banana bed extension.
Regs allow for 60% of wheel base (or max 3 metres) past the rear axle centreline.
So this gave me a measurement of 2520mm past centreline.
My wheel base is 4200mm.
In the following pics I have clamped a piece of wood in place to give me an idea of angle, length etc.
I have the wood at 2400 past centreline, leaving me room for a trailer tow hitch reciever. The truck itself is rated at 9tonne.
I am not sure, but I may even make the angle less, although I am confident Cobra will go up that angle ok.
I will also make/buy alluminium ramps for the last section.
Also will make a bulkhead, but push it forward as far as possible to allow room for a big winch.
The box section steel on rear of tray, is actually at max length.
