hey gixer I'm going to make my own rack after seeing yours it looks very well made,by the pictures it looked like it is held together by bolts only. were bolts enough to make it solid or did you weld at some spots? I have access to a welder if needed.It also looks like you used an aluminum track is this right? could you give me some pointers like the lenght of the tube going into the reciver,the type of materials(metals,bolts) you used,and a rough estimate on time and money and how much you think your rack weights?Thanks
