Greetings . . .

The rail iron is a good idea. But don't forget main line track is over a 100lbs per foot so you'll probably need help and hefty hardware. You might also find some 'yard rail' or 'siding' which is like 80lbs a foot.

Until you find some, I always used tube-sand in my two wheel drive. The bags are long and round. You tuck one in front of the wheel well and one behind on both sides. This leaves the entire center of the bed open for use. I have seen tube sand at TSC and Home Depot.

I have had 4x4 since I sold my '86 so I don't have to mess with this anymore.

Good luck.
