2008 Ford F-150 in San Antonio

I get in, turn the key, and suddenly I'm inexplicably dying to have a barbeque. It's a feeling I can't shake because I'm driving an otherwise stock 2008 Ford F-150 that's powered by liquid propane (LP), that ubiquitous grill fuel. (Methinks the column shifter should be a spatula.)

Our subject F-150 features fuel-system modifications developed by Roush Industries, the same folks who build all manner of high-performance Mustangs and contributed engineering expertise to the Ford GT supercar.
