fuel would be a issue for sure !!!!

I was talking to my buddy today who has a 09 2500 Dodge Cummins. He said the longest he has ever let his truck sit was 3 weeks in the dead of winter. He said he fired it up off the remote start from inside the house no probs at all.

If it sits for more than three months at a time pickle the motor.. if its not used enough the cylinder walls rust and the rings dont seat causing blow by. If you pickle the motor you can avoid this. Or you can just start the thing every week for 10 minutes or so to avoid this, way easier.

have you watched the show "fast and loud" they redo stuff all the time that have been sitting forever, a lot of them start pretty easily

We have had the turbo vanes rust to the housing (cat motors) on the 50' Searay after sitting for over a year, just took the intakes off and got them turning, back in business, probably fogging them would alleviate that problem.

Cant see it happening very often on a road vehicle unless left parked in the grass.

Treating for algae is the number one thing I would be worried about as it can be a pain to get that cleaned out.

You can definitely believe everything you see on reality TV

I see that too but starting is one thing running up to snuff is another

I try to drive my 2006 F-350 PS, (30k miles) once every 10 days or 2 weeks. Start our boats once a month if we don't run them in the last 30 days.
Everything keeps on ticking.

Ask this guy- 2005 Duramax with 6100 miles http://grandrapids.craigslist.org/cto/4320878837.html

I'd hate to spend 35K to find out though............even at 6100 miles with no heavy lifting all it's life .........I still think a diesel needs to work harder just to stay in shape.
