keep the jeep, buy a hitch carrier, can load it with your kill, coolers, stands, etc. Also can make/build, or buy the roof top carrier for more storage. Or buy a small 4 wheeler trailer, single axle type.
I have a 2008 F350 crew cab and just went to montana to hunt for 10 days. I loaded the back seats with food/clothes, guns, and ammo. Tool box with tools, straps and random stuff. Then I put my quad in the back and loaded it down. I had hardly any room to spare. Now if I had taken my wife 2010 4door Jeep Rubicon I would have had to take the trailer for the quad, more stuff then would have been on the trailer and that means more room in the jeep for people and movement. Plus I would have gotten better fuel milege.
In the end I would take the jeep next time.
