Ira , Thanks !!!!! Im thinking this thing will be a TANK !!!! The sides are gonna' be uninsulated , and just stained or painted...
I'll make insul/panels later if necessary...more weight ....
All parts will be simple , basic cabinets, shelves... not too much permanent weight like cab doors , drawers, etc , just a table/counter in the back (ESCAPE MODE)
Structure will be heavy (ouch !!!) but no frills to weigh things down ... the really heavy stuff will be carried in the bed of the pickup ...or the ole ladys' TrailBlazer
Sorry , I'm workin' on the paragraph thingie' , but I have to overcome spellering first .....

edit: I helped with your paragraph! Mike...
