so I don't know if this is true, but I heard that a heated garage causes rust. I live in sd and I think they use salt, or a salt mix. my garage stays a nice 75 degrees all winter. after a nice snow storm, I park it in the garage, and it usually is bone dry within an hour. even on a slushy day. will this promote rust on my frame or any other parts. what parts are critical? I have a slight undercoating, not a real thick one. but its usually dry soon after it makes it in.

 

Uhhh not really. A heated garage should dry off your vehicles under carraige quicker and dry vehicle = not rusting.

 

the salt on the roads is what eats away at metal. temperature shouldn't promote rust, just keep frame clean.

 

I was thinking washing it every 2 weeks or so when it gets above freezing should keep it clean?

 

it should. if you're driving in a storm, look for buildup of slush and snow when you get in the garage. thats usually where the salt will get trapped, build up, and eventually corrode the frame.

 

shouldn't make a difference parking it inside or outside tho?

 

not really unless you're parking on dirt/gravel opposed to pavement.
I don't have a garage and i have no rust on my frame. my shackles need to be replaced in the spring but thats a common part on all trucks that goes over time.

 

ya I need to do my shackles too
