Thinking about converting pickup to tow truck

[silverstreak]

Many of my friends and family members have come to rely on me to repair and maintain their vehicles. Recently I've been thinking about getting a car trailer or tow dolly. I've even considered getting an old Chevy tow truck or rollback as another project. (like I really need another) I saw this the other day I have been thinking about it ever since. http://www.liftandtow.com/products.html

I have a 71 C20 I was thinking about mounting it on. Does anyone on here have one on their 67-72 C20/C30? I'm interested on your thoughts / suggestions. Thanks.
