Storaging a truck with a vehicle cover

I have to store a truck for a few months outside of Hilo, Hawaii. It rains a little bit there. (150 inches a year). And of course, its warm and humid too all the time.

If I use a standard vehicle cover, will moisture accumulate inside the cover and cause rust problems. Should I just leave it outside so it can dry out after the rain?

I know a garage would be best, but I don’t have access to one.

Some one will be around to drive it occasionally.

You are quite right about the car cover. The problem is that moisture will accumulate inside and not have a way out. I had problems in this regard here in San Diego. Could be worse where you are as I’d think the combination of temperature and humidity could also lead to a mildew problem. One company you could trust for a straight answer is California Car Cover Co. Don’t have its URL handy, but a search will find them quickly. They make covers with many materials. Perhaps they have one that will breathe enough.

Tim, Thanks for the lead. Great website!

Good car covers breathe, but then they also don’t protect from rain. Many a new convertible owner has learned this to their dismay. What car covers primarily protect your car from is sun, wind-blown dust and frost. I think Hilo’s climate is pretty darn close to ideal for preserving a car, so unless this truck is some sort of antique with an original paint job, I wouldn’t bother with a cover.

Thanks for your comments, Jack.

I would consider a place like Phoenix to be ideal for preserving a car. Little rain, low humidity and no really cold weather. Just keep it out of the sun either with a cover or in a garage.

I’m worried about the very high rainfall and year round warm humid weather it would be exposed to in Hilo.

Depending on the value of the truck, and the reasonableness of putting up a temporary structure at the storage location, what about a portable garage?

I’m thinking something like the 10x20 canopy from Costco, should run around $200.

It can get windy. Securing the cover to the truck might be easier than securing a portable garage to the ground, but its something I was considering.
