RV Plumbing

I have had the unpleasant experience of the shower drain connection breaking at the P trap joint which I found out is not uncommon due to stress.
However, what idiot would install a P trap that is not removable on both ends, especially in a location where you only have a few inches to work. It has the removable end at the shower drain and is hard piped at the other end.

Just venting my frustration as it goes back to the manufacturer's old saying "We engineer for installation and not repair"
