Since you're coming from a toy hauler and you're thinking side exit, I'm kinda thinking you want to trailer the toy with it... If it's gonna be more than 2000lb, be careful with the C's, their towing capacity is often very marginal, and even then, a long overhang on them, if the rating is generous will make it a PITA. Also across Ford Dodge and Chevy, there's good and bad years for transmissions, which you'll have more issues with than motors methinks, if you get the "wrong" one and tow with it. I'm on the hunt for a cheap B myself, but having dumb ideas about liking rolling around under vehicles, (That is until I do it
) I would just "eat" the tranny issue and put one of the "good" ones in when it came to it.
