Lots of ideas but lets take a little comparison look at options. The advantages of putting it in the back are; 1) you need no lights for it, just strap it and go. 2) you won't have issues backing up, 3) as long as you have the means to load and unload, it costs least. If you have a buddy drive it, it's far easier and you have help and extra wheels but you have to contract a buddy and pay fuel for 2 vehicles. Now I do lots of my recoveries alone. Actually, all of them but maybe one or two. I'd lean towards the towbar route. You can get a uniiversal towbar for around $60. Add a lunette ring to it and you should be good. Astros have real bumpers so a jeep type bracket could be attached to the bumper. Magnetic towing lights can be retro fitted with 28V bulbs no problem so all you need is a trailer plug for the deuce. Going this route gets you there and back alone, can be loaded and unloaded anytime and anywhere, only pay for fuel for one vehicle and is reusable in the future. One humble opinion!
