Cool! I am also a teenage traditional bowhunter and recently got my first vehical, a Ford Ranger.
It seems to work real well up on the mountain roads and can haul all the crap, I mean equipment, that I need. Two quick tips that I found:
1) Not sure if yours is 2WD or 4WD from your post, but particularly if it is 2WD it would be best to throw some weight in the back when on gravel and snow covered roads. If you use some big chunks of wood then when you get a big game animal you can throw the wood out (and not miss it) and put the deer, elk, bear, whatever in its place.
2) I was hunting alone once and harvested a big bodied WT buck. Drug him grunting and groaning to the truck only to find out that I couldn't lift him by myself. I ended up having to quarter him up. Some friends later showed my how to let the tailgate down further, at an angle to the ground, which makes pulling an animal into the bed easier. Can't really discribe it, you have to release the cables that hold the tailgate up, maybe someone can explain better?
Congratulations, Juniper Bow
