I'm new to this forum but it seems to be a place where I can get help. My wife and I are planning on doing a LQ conversion to our Featherlite trailer. I've found all the items needed for the conversion but I have a question on how to run the gray water from our sink to the gray water tank. The sink is on the driver side of the trailer and the gray water tank is on the driver side. Attached is a copy of the floor plan layout. Do I have to take the 1-1/2" drain lines through the floor and then take it over to the tank (through the few I-Beams)?

Another way to route the plumbing is to install sleepers (floor joists) to elevate and insulate your floor. This will allow some room to install the pipes inside your LQ.

Yea I thought about sleepers, but with only a 2" lip at the entrance door, could I use a 1" pex tubing as the sink drain pipe to the gray water tank? That way I have room for the 1/2" plywood and the wood flooring. Do you think that would work?

Can you go through the wall into the first stall and build a cover over it to protect it from the horse ? The drain for a sink only needs to be 1 to 1-1/2"

Another way to route the plumbing is against the knee wall (bulkhead). A small rise in the plumbing above the flooring in this area, can be disguised by the steps or any cabinetry that is installed against the wall. A 1" pipe will work as a sink drain in an RV, if it is properly vented at its source. Usually its only contents are water and some soap. No solids or food contents should be attempted to be flushed from the sink with that small a pipe.
When we installed a floor in a DIY LQ, we were faced with a threshold of aprox 1 1/2" height. The finished floor was above that measurement, because we installed a one inch sleeper system, to allow the placement of a full one inch poly foam insulation under the flooring. A piece of flooring, ripped to the extra height, glued and finished nailed to the sleepers' edge, finished the flooring, and needing no additional trim work.
