The Seaflo Macerator Pump for Boats and RVs part # SE64FR is designed for RV use among other things so it will work great for this. It can be installed a few different ways but tapping into the existing waste valve is most common. I can't really comment on the exact parts as this will vary widely by application but you are basically just tee'ing into the waste pipe before the valve. I was able to find some diagrams for this online using a quick google search like "RV Macerator Pump Plumbing".
If you need any adapters and fittings, I have attached a list of some options below but you can also obtain most of these locally. The inlet port on the pump is a 1-1/2” MNPT and the outlet is a 1" Hose Barb.
