Flagstaff V-Lite Gray Tank Drains

I'm trying to figure out the best method of plumbing both of my gray tank drains together so I will have only one sewer hose connection to drain everything. I've been to a couple of our major plumbing supply companies and the supply of ABS fittings is very limited. I really need some input from other Flagstaff V-Lite owners who have made this mod on their V-Lites.

Thanks Fonzie but, I'm still not clear on how the 1 1/2 ABS was secured to the 3" elbows. I'll go lay under the unit and study on it as they say

I just bought a 30wfkss v-lite and found out I have the same issue. My dealer gave me a flexible 20' and a 10' flexible section of sewer line with an inline coupler and a "y"with screw clamps. Run the line back to your rear dump line, connect the 'y' to the rear section and add the final section into the dump hole in the ground. (Hint) do the front connection before you extend your slide out or you will be bumping your head.

rayo11, using the wye and two hoses is what I would like to stop doing. Call me lazy or whatever.
Thanks for the input!

Grey Tank drain!

I just purchased a 26 vfks flagstaff VLite and was wondering how to handle the drain problem. After pricing all the options I bought a sewer cap with a hose connection for the front grey water tank and a regular sewer hose system for the back grey and black water drains. When the kitchen sink tank is full I just drain it through a 5/8 water hose. Usually the bathroom tank and black water tank will fill at about the same time and with the flushing system that came with the unit I get things done without any problems. I use "Happy Camper" tank cleaner and after 15 years have not found anything better.

Thanks ddcar, I already have that setup. I was just trying to figure out how to drain all of the tanks from one connection thus simplifying the process another step beyond what I have now.

Thanks again!

I'm using the blue line hose ( x3) and a wye adapter for those few times I get a full hook up site. Not a big deal

Not that hard to do, just get an 1-3/8" hole saw, mark where you want the hole and drill it and then hand file or rotary grind to get a tight fit. Use ABS primer & glue and glue it in. Just to make sure, I also used silicone caulk around the connection and it's held now for 3 years. You do have to add another shutoff valve to the 1-1/2" line to keep the 3 tanks separated.
