This problem has been a bone of contention to me since I bought our camper in 2014.
I call this the ("MINI URINAL") as it is crotch height and so convenient for some butt wipe to make a deposit if you are disliked etc.

I hate to think these things can happen but they can and more dangerous or life threatening things can be put in there by kids or anyone! I contacted
Scamp about this design, but guess what?
They have been building these eggs for years, why change anything that is not broke!! I have made many upgrades on my own but still think that builders of RV's, Trailers should take a look at features of danger and safety suggested by owners and make these items a priority to correct to show their respect for safety considered by Purchasers. Yea, Right! Anyhow I will finish that problem and tackle the Mini Urinal soon, just been busy. So darn stupid!!
