I like to bring out game animals whole to transport them to our processing setup on the farm where we break them down and process them like livestock in a clean, butcher room setting with running water, tables, etc) so we prefer to bring out game animals whole.
Im in my 50's now and hunt solo most of the time so I upgraded my bear and deer loading gear for the truck because loading a bear or a large buck into the bed of a truck with a high bed is not an easy task for a single person. I hoped to make it easier.
After trying and testing out a variety of methods I ended up with a 7:1 ratio block and tackle (freshly re-strung with 115 feet of rope) and an 8 foot (trough style) ramp to keep animals centered rather than sliding off the edge. Here is a 1 minute video of the final product and a test pull of 225 lbs (I think it was actually more than 225 since the crate corners really dug into the ramp increasing the friction) Either way, he should be good to go for any animal he kills while hunting alone.
