I'm interested to hear how it turns out for ya JS. I've been using a 104gal in the bed tank for 6yrs. 35gal + 104gal = 139gal total X 20mpg = 2,780 miles!!! (running light) Now I've got a camper and need to rethink how to stuff at least 100gal under there somehow. (I get into some very remote spots AK / CA)
