I'm not surprised that you're having performance problems with only one truck pickup. It would be worth the effort to add pickup to the front truck. That would likely cure 90% of your pickup problems. I would even be willing to look at that for you if you cared to send me the units. I hate to see you giving up on those with all of the work (and money) that you've invested in them when I'm pretty sure they could be made to work well. A PM would do it.
