2nd Black Tank System
Hi! We are new to the RV world and just purchased a XLR Boost 37. We have emptied the black tank and then rinsed with the gray tank BUT we are unsure the best way to manage the SECOND black tank located in the back of the camper. It does not have a grey tank reserve. Does the water flush include the second black tank?? We havenít found any information on how this system works!
