The basic idea of a heat exchanger for a shower is very simple:
Get a container to hold the shower (hot) water that can handle some heat - stainless or ally would be best but plastic is OK. Need to be able to fit copper heat exchanger pipe inside this, and need to be able to fill and remove shower hot water as needed.
Most boat heat exchangers are a stainless box able to hold at least 20 litres (but stainless not essential for a 4x4). The box has a fitting at the bottom to draw off the hot water (for shower). First the 5 sides of the box are made (all but the top) and the top is made as a separate piece. A copper coil is bent up into as many loops as you can fit inside the box, then the 2 ends are fed through holes in the box and the outside of the 2 copper pipes brazed to the stainless lid. Then the stainless lid can then be welded to the rest of the box.
Hot water from the cooling system of the boat/4x4 engine runs through the copper pipe, and heats the water in the "box".

My old man made one years ago.
We think it had way to many coils in it because it was just too hot.
Made from copper tube, 5 inch round i Suppose, with copper coils inside it.
Works good, just too hot.
Am trying to get it modified at the moment to fit to my patrol.

Like the following drawing, sugest you get the local fab shop to weld up an end cap on one side and flange the other so it can be repaired....sugest 4" alloy piped, and standard domestic copper pipe they use for plumbing1/2" [plumbers????] then tap the holes in 19mm bsp as it is standard polly fittings from irrigation
sorry crap drawing and it wont play nice so wont link
