bhum, I'm pretty sure most of the hitches you see on 5th wheels are custom made. While Heartland/Lippert don't reccommend it there are many owners with hitches. I don't know of any pulling vehicles though. Two things, make sure the Samurai is capable of being towed with all 4 wheels on the ground and please get some aftermarket brake equipment for it. I know they are light but I'm sure you know what can happen.
