this is my first post on here actually, soo.. hello, ive been runnin a baldwin remote filter/ wallbro 392 inline on my truck with a bypass regulator for a few weeks now, seeing good results, awesome pressure, but it is definitely worth your money if you can get your hands on an airdog, i spent more money and time building my setup for the truck than it probably would have taken to install an airdog, i tally'd it all up and i was around the 700 dollar mark after all fittings, hoses, pumps and filters, along with small tools, and the airdog does something this setup can never do, remove the air! if i coulda gotten mine across the boarder (****in ups had the wrong paperwork) i totally woulda ran the airdog, but the wallbro setup runs awesome as an alternative
