I know the area well, I used to live in Spring Hill. I never had a problem collection more oil than I could use there.
Frybrid's biggest drawback is that it's a one man band - and sometimes patience is required in order to remain a satisfied customer. You can get a lot of help out of the owner, he drives a Dodge 2500 himself, so he's very familiar with the Cummins engine. He tends to send out orders in batches when they are complete - so when his suppliers take a while to fill his orders, he takes a while to send out his product. Set your expectations to this and you may become a happy customer.
His systems are well thought out and pretty robust. I've bought cheaper kits from other vendors and been dissatisfied. I've built several of my own and not saved much money over a Frybrid kit. If you haven't spent a lot of time researching and experimenting on your own vehicles, I'd suggest going with a well made kit and I'd put Frybrid on the short list of acceptable choices.
