panel templates for cargo van? Help

[sprinterjim]

I just began a project to panel & insulate my 07 144 V6 diesel cargo area. The door panels were easy using FRP & a saber saw. Looking at the overhead & sides I thought I better get some advice. Is there any templates for cutting peices? Does the overhead in the cargo area require any extra braces? I was hoping not to have to make templates, somebody has been there and done that and I am hoping they will share. Thanks.

Any sources for templates/DIY panels inside the cargo area? I see no replies to this thread.

I just picked up a 3500 high-roof with the 144" wheelbase and short van body. Completely empty shell in the rear. We will be installing a bulkhead and some limited shelving, and I think some insulation is in order.

Had a vision (perhaps a fantasy) of creating the IKEA edition Sprinter work van -- birch plywood panels everywhere, some hidden lighting, maybe a coffee pot...

Any other nuts out there?
