good info - i don't carry extra belts or coolant....but i will now (thanks for the reminders),
i do carry extra fuel filters.

thats quite a bit of oil....boardering on 20 % of the overall capacity.

i usually have a gallon of oil on me, but have never had to do more than top up (2 quarts) and that might occur once or twice a year (depending on use)....if i need 2 gallons somethings SERIOUSLY wrong.

i have a self prime button on the (external) filter housing...crack the bleed screw on the filter and give it a few pumps (you'll hear the air being expelled...cant remember maybe even fuel comes out, shut the bleed screw and twist the key).....even when i drained the primary (engine mounted) filter i didn't have a problem w/ priming or running rough after a filter change.

that damn air filter (suction pressure) gauge has never moved on mine...but i agree its a good idea to look down that filter intake for obstructions or worn filter (same thing for my f350, which uses a similar gauge...never moves).

that tire pressure could be a bit low - I've notices some exterior tread wear on my steers...like they're under inflated when i run 'em at 100.

best way to determine air pressure is via the scales.
