Drill holes in the handles for a pin when you want it extended out! If you havent done it yet load that puppy down and let it bite your finger one time!
Reason I said framed ruck is because you can get them pretty cheap and they are very washable.....Id say you could get 80# a trip. buggies are the best but there are places they can make for a ruff trip. Ill send you a pick with the two hogs I loaded at the same time. Moved em about a mile to the truck.........was very tired!
Live in North Idaho and must say that cart would be not be useful in much of our area. Alright on logging roads and such, but the brush here is just too thick for most cart applications.
The pack subject is interesting. I will not use an external pack after using an quality internal pack. Frame packs don't fit the body and are way uncomfortable.
Look at packs from Kifaru and Mystery Ranch. Get some Kifaru game bags to keep the pack clean, and your set. Those old externals and packboards bite into the shoulders and are not great for positioning weight. Get modernized with a quality pack.
Don't feel too bad about overloading the cooler on the ground. My buddy and I did that in 2005 when we stuffed an entire boned out cow elk plus ice in a 150 qt cooler on the ground. Luckily we were able to drag it over to a spot where the ground sloped off and we could back the truck up to it. We only had to lift it about a foot but I thought I needed to do the old "turn your head and cough" test after it was loaded! [img]/ubbthreads/images/graemlins/grin.gif[/img]
