No Hot water and don't know why

In my 39 years of having an RV this is a first. We are camping for the first time this season and I'm having a problem with the hot water that has me totally baffled. To start with I did my usual winterizing last fall, blew out the lines, bypassed the water heater and opened the water heater pressure relief valve and pulled the drain plug and left it out all winter. When I put water to the system everything seemed OK with no leaks. I opened the water heater by pass valve and thought I was set. WRONG... I turned on my water heater and could hear it running.. I open any of my 3 hot water faucets and I get cold water and it acts like there is air in the lines even though it's run for several minutes. I loosened the drain plug in the water heater to check and the water is hot in the water heater. For the life of me I cannot figure out why I'm not getting any hot water out of my faucets. What am I missing???

recheck the bypass valves and also check that the handle is not just slipping without turning the valve.

Assuming you have put all the by-pass valves back in the proper position--its possible that the in-line check valve at the top oulet of the water heater has failed. They are made of plastic and when they fail, they usually block hot water from leaving the tank...

If it were the check valve he would get no water at all

Not always true--if you check a mixing valve fixture, the cold water fron the other side will mix at the faucet....still think its the check valve--unless your by-pass valves are still turned??????

Not always, mine was trickling hot water, both check valves were degraded. Its at the shop now to remove them.

Long shot, but do you have an outside shower with a quick connect fitting on your rig? Check and make sure the H & C handles are both closed. If they are left open, it will cause hot & cold water to mix.....

To all of you Thanks for your input. Although it shouldn't matter forgot to mention that this problem is on a 2003 Holiday Rambler Vacationer Motorhome. I will tear into the check valves this afternoon and see what is going on. Have a great Holiday weekend to all of you...
