@Jared341: It took a while to upload this pic. Since then I have added chain tensioners that have added to the wrap, but I may want to add even more wrap. What do you suggest? The axles are just 1/2in shafts with snap rings on either side
@O'Sancheski: Yeah I realized that after I posted it

Do you think having the center wheel driven is useful?
@Chrisisme: Yeah we have a lot of experience welding in our shop. As long as you have a good welding jig the chassis will stay square.
@EricH: Good point I will work on a redesign
Thanks all for the excellent input!
