We've been here in the Columbia River Gorge on the WA side since thursday. Although we've been taking advantage of the camps showers a few times, so far, we havnt had any back ups. Will be dumping before we leave tomorrow for the coast. Will have sewer there so we'll be dumping more regularly and i can figure out what the capacities are.
Hold that thought, at 3:30 am, my carbon monoxcide alarm went off and there was a strong sewage odor in the lav. I silenced the alarm and vented the 5ver. Turned on the ac fan, and left the door open the rest of the night. So i guess that 4 days is the limit!!!
