+1 on the Salt last month. In fact, the USFS guys were stoked on the design and wanted to know where to get one. Super happy with mine....think we can all testify it's as ash-free as anything, if not more so than the ghetto oilpan or trashlid setup that somehow is still acceptable.
I've already heard this passing WW inspection more than once, so am quite surprised to hear about a recent denial and too would appreciate if the rangers would get on the same freaking page. This pan meets the regs, as written, so if they are going to get capricious about things...outta change them for clarity.
