Yes, it would be a re-configuration, it would no doubt be expensive. Seems I saw someone on a forum once who had done it. But can't find it now. The black tank is in the rear of the rig, under the back bath sink. It would require the front bath to be remove and sealed up. Then the back bath would have to be reconfigured with the toilet next to the shower to drop straight to black tank and a lavatory that wraps, rather like the Tiffin 36LA does. Seems like it could be made to be a straight drop, one toilet system. However, just trying to see if anyone else has done it... New pump is working, however goes off about every 10 min, which of course means air leak somewhere in the system. So going to take it apart again today. Hate this system, would not recommend, would never buy again and will warn others, 2 bathrooms, NOT worth the hassle. Love the RV, but not this system. Hate to give up the floorplan, but that's the next step.
