fresh water tank issue/question
Hi there hoping for insight on these questions, have BH TT I have never put in any water in fresh water tank via water inlet, have always removed drain cap on tank when I winterized. I day last summer...

Water coming out the city water inlet would be due to the check valve in the inlet assembly being broken or out of position or otherwise not working properly. The first thing I'd do is see if I could tweak it with a finger or something. If that doesn't work, an easy quick "fix" is to screw a plug/cap into the hose connection so water cannot come out.
Water filling the tank from the fresh water connection generally means that either a fill valve is not shut (if you have such a valve, not all RVs do) or the check valve that's incorporated into the water pump is leaking. The latter is often caused by a tiny spec of debris in the diaphragm of the pump, and if so may fix itself with some pump usage or with disassembly and cleaning. If the pump works decently otherwise, and the check valve can't be cleaned/fixed, installing a separate check valve on the pump suction line is a reasonable fix too.
The other hose sounds to me like it may be the vent hose for the tank, though it's hard to say without more details on where it goes from or to. If it is the vent hose, you want it to have a high spot above the top of the tank to avoid having water overflow through it when the tank isn't full (and, potentially, to help avoid siphoning a good portion of the water from the tank). A small kink in a vent line isn't going to cause major problems; there's a lot less resistance to airflow than water flow for the same size opening. Of course, if it's pinched shut or nearly so, that's a different matter entirely.
