We plug into the garage 120VAC 20AMP service all the time here but do use a HD extension (10-3) extension cord to run out where the trailer is parked. Then we use a RV30A-15A "DOGBONE" type adapter to plug the trailer 30A shore Power cable into it. I was never able to use the small round adapter as they would start getting hot on me in a short time. The long cable dogbone type adapter from WALMART is what I use. I also have one of those RV 120VAC plug-in VOLTMETER that is plugged into a receptacle in the trailer where I can get a good glance of the 120VAC voltage level. This AC METER has a GREEN AF ZONE identified on the meter scale. If this is reading within the safe zone then you are good to go...
Sounds like the initial reason for the blown fuse is the on-board converter/charger had to put out maximum DC Current for the trailer battery to begin its re-charge. May have been too much current being demanded when this happened. There may have been other 12VDC items turned on the inside the trailer as well... The ceiling lights run off the 12VDC circuit and each of those automotive bulbs in the light fixtures can draw as much as 1 AMP DC current. Having three or four of those ceiling fixtures turned on usually have dual lamp and that could add up to around 8AMPs of DC current. Need to change all of those out for LED lights once you get setup for camping.
To check the converter/charger what we do here is measure the DC VOLTAGE on the battery without being connected to shore power and if the batteries are fully charged they will read around 12.5-6VDC. Then connecting the trailer to shore power the DC VOLTS on the battery terminals should jump to 13.6VDC indicating the on board converter/charger is connected and is running ok.


I can NOT use these types of RV30A-15A adapters

Your 2008 model trailer however will not have a smart mode converter/charger unit on it and you really should replace the older converter/charger unit for a modern multi-stage smart mode charging unit. Find the model number of the on-board converter/charger and check it out online or list here. The new smart mode converter/charger really take care of your batteries for you.
Since your 2008 model has been sitting for awhile at the dealer it may have boiled out some battery fluids -probably should check the fluid levels and make sure they are above the internal battery core.
Buying something USED is a great price sometimes but doesn't mean much when you have to do a lot of maintenance and replace things to get everything back up to good operating conditions. This is why the previous owner got rid of the trailer in the first place - things have started to go downhill perhaps... Let the next owner worry about things
Always a good idea especially since the trailer is used to start off with camping overnight in the driveway for a couple of nights to make sure all major systems are running good. Not much fun getting caught with bad things when you are hundreds of miles from home base.
