Interior restoration - Veneer

[tjdixon911]

I'm in the process of restoring the interior units of my camper - I want to re-veneer them

I've got a unit circa 2m X 1.5m - most of the veneers I can find seem to be 300mm wide - does anyone know if I can get a single sheet to cover this or will I need to abut several sheets and will the join actually show if installed well?

Any recommendations for veneer manufacturers / suppliers.

Also I've seen both iron on and glue on, I'm assuming the glue on is best as easy as the iron on option seems..
