Anyone have experience or recommendations? Cabelas has Foreverlast, and I also found a Killshot brand.
Saw a Buc-up on YouTube. I realized it's harder to yank a good sized deer into the bed of my Ranger than into a pickup. Tailgates are same height, but the Ranger has less room to get a toe-hold to heave that big boy up and in.

You can get game baskets that go on the receiver hitch... Much cheaper and very easy to load big game by yourself

Sounds like something to look into. Any recommendations for the game basket?

This is how I addressed that issue with my Rhino. Perhaps you can do same with your Polaris.

Rhino game loading system.

Winch-up Swivel Deer hoist that fits in the receiver hitch at Sportsmansguide is $80.00 for members. I have one for my truck and it works fine.

You are going the right direction with the receiver winch. Used one on my Rhino the last 5 years. Absolutely the best, easiest way to get the job done.

I make game hoist which can be used in either a truck or ranger. I also made a bracket for my ranger to use a 1500 lb. winch someone gave me. I used to use a sled but have gone to rollers recently. You can see both on my website, and on You Tube.
