1- has anyone converted the 4.7L over to propane?
2- is there a kit available for it?
3- what kind of real world mileage would propane get?
4- how would the torq curve be affected using propane only (not a dual fuel) on a NA motor?
I know the rock crawlers are big into these kits for CJ's and old Yotas, but I have not seen anything on the newer stuff.

Look in the photo gallery for photos posted by "arthur"...he lives in the Netherlands (Holland) and posted several shots of a conversion of an '04 V8 Stepside to run on LP Gas (Propane). So apparently it can be done...though whether or not it can be done in the US is possibly an entirely different matter. For some reason, "arthur" has seemingly only logged into/posted in the TSPhotoPost...a member search on TS.COM didn't turn up that user name.
