When I eventually build my trailer, I'll give you a call to buy one of those couplers.
One thing I've learnt the hard way is if you've got a good thing (design or concept) is never to let the info out until you're ready to start selling.
I could have been sitting pretty now if the info wasn't leaked.
A good mate of mine is a cabinet maker and between the 2 of us we developed a mobile camp kitchen the size of a 50L fridge (Engel type) and we were busy finalizing everything but unfortunately my mate has a bit of verbal diarrhea and the info got out and suddenly the patent was registered by someone else when we applied
. Long story !!!
I've still got the original prototype sitting in my garage.
Takes a CADAC 2 plate burner, russian kettle, 6 stainless mugs, 6 stainless tumblers, 6 stainless plates, 6 forks, 6 butter knives, 6 steak knives, 6 table spoons, 6 teaspoons, 3 sealable containers for coffee tea & sugar, 1L long life milk carton, small pantry compartment for food items, wash basin, 2 small pots and has a work surface.
The whole thing was going to be aluminium, lightweight and waterproof.
The idea was to have it drop onto a fridge slide or just loose in the back and when you stop for a quick break, just whip it out and make coffee and snacks.
We used it all the time when we traveled.
Thinking you can trust someone with the info just gets you properly buggered.
