Hi, i am looking at making a new tray and have a trayon camper which is 2200mm long, but i also want to have a aluminium box madeup for a engel fridge with slide.

The fridge box would need to be 450-500 wide so the tray lenght needs to be approx 2.7mtrs long, so can anyone see any potential problems with this idea.

Also thinking of mounting a removable wheel carrier on the rear of the tray directly behind the camper.
Camper weighs only 650kgs when loaded with 70% of weight slightly infront of rear wheels.

Have got the idea from Shepparton 4x4 centre, he has same setup but is on a cruiser.

Will appreciate any feedback.
Cheers
