Just recently joined this site so hope this answer is not too late. You can check eBay to find recent prices for the vehicles. Your 65 Ford PU could be worth $4-5000. depending on overall condition, the engine size, and if currently running. The Malibu perhaps up to $2500. The bike, you should not have a problem if you put grease on all the moving parts before your leave, this will prevent rust. Tires you may have to replace because they will probably dry rot before you get back.
Wish you the best and good luck on your Basic training.
