What is the issue? The dump handles are in a crappy place, but not covered by the underbelly. Are you looking at the wrong things? You do have a Delta, right??? If so, look at the slide. You will see three stickers. Black Tank, and two stating Gray Tank. With the slide in, you should be able to reach all three handles. If the slide is out, you just kneel down and reach towards the belly side. There will be three metal handles sticking out. Those are the dump handles. Would you like a photo? There’s no way those three handles can be under the underbelly material! I assume all the Delta models are the same.
did you have remote dump handles Installed??? If not, they are not covered by the underbelly. Unless you have a different Delta than our 262rb. Oh, wait….you must have a bunk house, and I didn’t look at them. The quick glance said yours and ours were essentially alike, however. Yes, there are “remote” handles you can have installed: mechanical (spring cable) and electric. But the stock handles likely are the same across Deltas. Bathroom and kitchen placement often impact that, but BH Deltas have rear baths with midcoach kitchens. At worst, since you have a BH, they might have split the grays with the black tank handle close to one of them. That would mean having to carry a “Y” fitting for sewer hoses. I’m taking our 262rb to the delayer tomorrow. He did have two BH models when we picked up ours. I‘ll check them out.
