Greetings,
We've been living full-time in our Bighorn 3970RD for a little over a year. For a number of reasons, mostly convenience, we recently started planning on the swap-out of all the original cable operated wastewater dump valves to electronic actuated. After much research, we settled on & purchased a set of Drainmaster Pro series electric waste valves and will soon start on the install project.
For reference purposes, prior to dropping the coroplast to locate the valves & general plumbing layout. I contacted the factory, gave them my VIN number and requested a drawing which I have embedded below for anybody needing it. The factory rep did state that slight differences may exist from the drawing vs what was actually installed on the production line. So far the only thing I've noted different is one vent line. So your mileage may vary.
