excellent You are my kind of guy probably somewhat of a packrat. How many miles do you figure it will take to break even?

I am hopeful that My front mod on my camo van will pay for it self in one year. About 8000 miles.

brackets 0 free, taken off junk stuff
hinges 0 free, taken off junk stuff
Primer $5.00 Used 95% of one can
paint $14.00 bought two 8 oz cans used 1.5
clear coat $5.00 used less than half of can
Total $32.50 (only what was used = $22)

design time 2
build first bracket 2
build first skirt 2
mount and tweak first skirt 1
paint first one 0.75 (not counting dry time)
build second brace 0.5
build second skirt 1
mount and tweak second skirt 0.5
paint second one 0.75 (not counting dry time)
Total 10.5 hours

planning 0.5
first ABA test 3.5
coast down 1.5
second ABA 2.5
Total 8 hours

Costs for testing:
gas 7 gal
cost $19.00
miles 280

So in total I have about $50 invested in skirts and testing. I also have 18.5 hours invested in making and testing them.

Testing takes a lot longer then I had thought But good data is nice to have (and share)
