Just bought our first camper. It's a 2017 Gulfstream Conquest 198BH. I seem to be learning things ok, but one thing has me stumped. I don't see any way to monitor the holding tank levels. Other than a flashlight down the toilet, is there some way to tell? Or am I just not seeing the gauges
Suggestion . I took mine out in normal configuration. I did not use the bathhouse for showers or potty. I monitored this for the week I was out. I have done this 3 times and I have figured out about how long I can go without dumping black or grey. Hope this helps.
