Thanks everyone for the feedback....
Since the connector from the hose to the faucet assembly only left about 1/8 inch between the hose and the back wall of the assembly box, it was impossible to get leverage to tighten the hose to the faucet connecter. Adding to that, the connector was smooth with no way to get a wrench on it and needle nose also didn't get the connector any tighter...
Looked where the assembly box was connected to water (which on the VEGAS 25.2 was under the couch) and saw I could disconnect the water hoses, then remove the nuts holding the faucet to the assembly box. after removing the faucet, it was a simple thing to tighten the connector...
I just am still gun shy about disassembling my RV (too much anyway) Especially when it concerns water.
