Fifth wheels have the same problem. Our drain is undernieth near rear axle. The valve is reachable unless you have the slide open(which we always do at home), then you have to crawl under the slide to reach it. I carry a slip on adapter so I can hook it to a long water hose to drain. If it is just water, I direct it to a tree in the yard. If it is a strong bleach solution for disinfecting, I direct it to the drive so not to kill grass/plants. Our RV port has a gravel floor so I dont want the 50 gallons to just go under the trailer.

I changed mine also. Did not like water dumping under MH. I put a hose conn. on the valve. made a 3/4"PVC pipe extention that extends just outside the compartment. There I have a 90Deg. elbow with another hose conn. Hook on hose and run where I want it too. The reason for the PVC pipe was to make it easier to conn. to valve. Can do this without crawling inside compartment. open/close valve using awning hook.

Ever had your water tested? My Owners Manual calls for a disinfecting procedure which I do about every six months, including the lines. Between procedures, I drain & replace water about once/month or more. Bugs grow, particularly in warm weather.
I also have a garden hose adapter; works but is very slow to drain.
