I really like my Ameristep non-typical aluminum cart. It carries in as an easy backpack (maybe 20" x 20" x 6"), unfolds, has sturdy canted wheels, centers the wt., and works awesome. I hauled out another #220 field dressed buck this year (yup- weighed it!). I am 50- two back surgeries and inner ear disease- I need to be careful hauling and this works well.
I know there are larger carts out there and take more wt. off- but the down side is they take up so much room and are not portable.
PM me- I can tell you one of the best deals out there. $70 cheaper than other places.
