Normally goes for $30, but there's lightning deals all the time that bring it down to ~$20. I just go to homebrewfinds.com every morning to find out about those things. (thanks /u/homebrewfinds!)

You could try one of the mini dehumidifiers- http://www.amazon.com/Gurin-DHMD-110-Renewable-Wireless-Dehumidifier/dp/B00ANX1PAI/ref=sr_1_11?ie=UTF8&qid=1413721285&sr=8-11&keywords=mini+dehumidifier. I keep one of these in Boo's enclosure at night. Or, on days that are VERY humid (like they are at times in Connecticut) I put a mini electric dehumidifier in the corner of her enclosure- http://www.amazon.com/Ivation-DehumMini-Small-Size-Thermo-Electric-Dehumidifier/dp/B00GZ6OI8S/ref=sr_1_4?ie=UTF8&qid=1413721285&sr=8-4&keywords=mini+dehumidifier. These are very quiet and I had to use it earlier in the week when the humidity was at 90 (no lie- uggghhh). It did help with it. It's worth a try.

I saw one of these at the local gun store (but for 20+ bucks) I'll probably use that, cause you can just plug it in for a day, then stick it in the cabinet until it's absorbed all it can, then plug it back in. Saves me having to buy things repeatedly.

With regards to a thick grease, what do you recommend?

Like one of these guys? http://www.amazon.com/Gurin-DHMD-110-Renewable-Wireless-Dehumidifier/dp/B00ANX1PAI

Anyone have any thoughts on a dehumidifier like this?

Since his camper is a fairly small, I imagine this might help absorb passively.
