If it seems to be ok plugged into a 50 amp outlet but when you add in the 50 - 30 converter and plug into a 30 outlet and the voltage drops, well the converter is a good first place to start.  Bad connections are bad.  They cause voltage loss, heat and other problems including burning up you new 50 amp landline.  Get a new one.

I am thinking converter too....Just left my kids inheritance at FOT, oh well this is a great coach...she deserves the best.

I believe it is the original converter too.

Time to start shopping.

Good call Brett, checked coach and found the block heater to be on.  114v in the coach now... amp draw is .6 amps

I want to thank all of you for you ideas and help...This forum is a wonderful resource with so much knowledge.  I appreciate you all  very much.

John, I would still be concerned that the voltage drop with the block heater turned on was 17 volts (114 to 97)  Check the plug where the block heater is connected.  Many have discovered a melted plug.

I will, going to Galveston for a few days tomorrow, will have time to look her over...In the past, it seems the voltage starts low and works its way back up very slowly
I sure wish it was fall..

If your batteries are low and you plug in with the charger on you could be putting a lot of amps into the batteries for a while. Make sure your alternator charging is up to snuff.  With a res refrigerator the load is higher than it used to be.  I swapped my LN 160 amp alternator out for a Delco Remy 240 amp brushless alternator and a zero voltage drop isolator.  Way better.

She had been at FOT for a month.  Batteries are in good shape, but I do not believe they kept her plugged in.  Oh well she is home now and I can keep an eye on her.  Going to Galveston for a few days, so will be able to check things out....Thanks again for all of your help.
