When camping and hauling I usually use an old external frame Camel. It is very adjustable for body size and can carry a lot of stuff. I once hauled four cases of beer with it and still had room to strap my personal gear to the top and my bedroll underneath. I bought it more than twenty years ago for about $70.

Hauling that much weight would probably kill me now. But the pack is still going strong. The hip belt and shoulder pads are still good.

In my vehicle I have one of two much smaller day packs of undistinguished origin and manufacture.
