Mod to low point drains with mixing valves?

I would think that you could just leave those valves open and add on to the exposed ends where they drain out. You might be able to rent a crimping tool from Home Depot and get the extra PEX pipe, valves, elbows and crimp rings to do this. Should not be a big deal job. What you mean by "mixing" valve I am not sure.

Faucet

OK, I don't understand why you would put a faucet on a low point drain line? Am I misunderstanding what you are trying to do? Pardon my intrusion.

Just put sharkbite valves or 1/2" male threaded hose bib on the pipe beneath the trailer. It will give you a hose connection beneath the trailer. Use a wye hose to tie them together if you want to mix the hot and cold. It is an easy way to create another hose connection.
I did something similiar on my last rig and it worked great

Sure would be handy for me to have a hose on left side...family of RV's 6 or 8 having a big "pot luck" or one of our favorite boondock spots, or another place you have to be first one at fish cleaning station or you're sol. Not so much the space to clean fish but one faucet at a fish cleaning station makes it a little bit hard. After making a hose connection I'll just run hose over to cleaning table with hot and cold water:) and when done cleaning and canning move back to regular campsite. Another spot...one in-law has a road trek with small tanks. I could hook up to standpipe and could transfer water to him. Did I mention a lot in Yuma that gets that very fine dust, hose off patio:) But don't think I'll have the water pressure for that. Anyways lots of times a hose connection would come in handy for me. Now I'll have to find a place to carry hoses.

I connected up a hose up one time to my OEM outside shower wand. And broke it first time using it. Outdoor faucet is Phoenix brand. Also known as plastic junk. Other options would be good for me.

You could extend both hot and cold lines over to the side of your RV and add valves to each, followed by a mixer "Y" fitting with the single hose fitting. Then leave the drain valves inside open and instead use the new exterior valves. But you need the "mixing" section after the valves, not before. Using a "mixing" "Y" to combine the hot/cold drain lines into a single valve hose bib would result in your hot/cold water inside the RV being mixed. You won't get "hot" water at your kitchen or bathroom any more.

I added a male hose fitting to my drain for a free-standing outdoor sink. It is on the pressurized system, and once my outdoor sink/table is set up, I use a short hose to tie it into my RV and open that valve. Now I have running water at the sink; but only cold, as my outdoor sink table only has a single valve faucet.

Easiest option for you would be to install a hose quick-connect at your outside shower at the control valve, not the end of the shower hose. Then you could quickly plug in either a hose or the shower head, and still have full temperature control for either the hose or the shower head.
