Well I hope I have found out why the 240v heating is inoperative on the Truma heating.
A blown 10amp fuse buried behind a panel on the boiler, that was jammed in by the converter between the side of the van and the bed mounts/base.
I had to dismantle the entire bed, ducting, gas and water supplies. Release the boiler from its floor mountings to allow space for the removal of the electrical cover on the boiler.
Fuse ordered and hopefully when fitted will bring the boiler to work again. 4.5hours so far.
Photo's are not great, apologies for that but I thought you may be interested.

The only way to isolate the gas was on the tank. Valve underneath this cover.

Boiler on its side to allow access

Upper electrical panel with the 12v fuse which you can replace by just sliding off the outer/small cover.

You need to remove the larger cover (two screws at top and clipped on the lower edge. You need to swing it out a far way to clear the boiler parts to release this cover.
The fuse for 240v operation is 10amp slow acting, interrupting capacity H type and cost just 31p.
