I am a newbie RV owner.<br/><br/>Question for Group.<br/>2 Low point drains located:<br/>near Driver's side on outside of Rig<br/>and<br/>inside last basement storage on passenger side at rear of Rig. Inside there are 2 valves. Directly under valves/under rig are a small blue hose and a red hose. <br/><br/>Wanting to know what each low point drain is for?<br/><br/>The Manual...
