First off: I do not own a car for myself yet, but I will have a WRX soon (within a few months). This is hypothetical knowledge that I will eventually have to put into practice. For the sake of this, assume I have a 2002 WRX sedan.
So, the HS bowling season is officially over for the year. During this time, since I can't drive myself (NJ permit allows me to drive... with a parent in the shotgun seat), my mom would load my equipment into her van, pick me up at school, and drop me off, with my equipment, at the bowling alley (long story as to why there's no bus and I can't leave my stuff in the school).
So basically, for next year, I want to be able to drive myself and not have my mom strain her back on my 70 pounds of bowling balls any more. However, a few things need to be taken into consideration:
* I'm going to be parked, engine off between about 7am and 2pm.
* I'm not going to be parked anywhere within useful distance of an electrical outlet or other source of electricity.
* Ideally, bowling balls should be kept at room temperature of the bowling alley always. a few degrees below is okay, but leaving them in the trunk in the winter all day could lead to BAD things (cracking)
* I have decent electrical skills, but not particularly in the context of a car (never put much work into a car besides learning how to check oil - once I get this car, I hope to become very skilled)
* I should be able to take the balls out of the trunk and still use it for other purposes
* I should be able to leave the car parked without this thing on, if I decide.
So basically, although I have some ideas,I'm not entirely sure how feasible they are, and I'm wondering if others have other ideas... My ideas:
* Trunk heater. Pros: more seamless deal, just have to drop my bags in there and everything is done. Cons: need to heat the whole space, not just the balls. Also, would probably be crazy-hard to install.
* Ball warmers. Run a 12v aux jack that's always-on to the trunk, grab two electric blankets (one for each two-ball bag), set them at their lowest setting or so. Pros: confined to just the space of the balls, so most efficient. Would also have easily-accessible voltage back there for other stuff. Cons: have to wrap the balls individually, which is hard and takes time. Also, it seems like those blankets draw a lot of power... although I don't know how it compares to the power I have available from the battery.
Any comments on this?
