My truck has recently developed a problem starting when left to sit for a day or so, I have been leaving the block heater plugged in and it starts fine, but am afraid to do any camping with the camper we just bought. New Hpop, ICP, IPR, and both CPS's. It does puff out a bit of white smoke when it starts, but it has pretty much done that since day one. 04, 170K mi. Thanks for any help.
