My camper is a converted panel van with a sliding window behind the drivers seat, window made by Leisure Windows and isn't recessed.
The panel around the window is pretty rotten so I have the choice of trying to patch around it or replace the panel.
If I replace the panel I need to find a panel-van panel and cut a new window hole in it.

Trouble is I can't find anywhere that sells these panels (offside, NON sliding door, above waist).
If I patch around it I'll likely end up with a leaky window where the patches overlap.
Third option is to cut a window hole in a sheet of steel and weld it in as a big patch.
Has anyone else suffered the same problem? I'd like to hear how you solved it.
Searching to forum shows a fair few posts about fitting conversion windows which helps, but I'm still swithering.
TIA.
