We camp out in our 30AMP 5th wheel all the time plugged into our garage 20AMP service using an adapter.
We can run just about everything in the trailer but have to watch what we have ON at the same time. Air conditioner and microwave are heavy current items for us. I have 50-feet of HD contractor (10-3) extension cords running to the trailers.
Its a great get-away for us. You sounded like it was something wrong by staying in your 5th wheel while in the back yard. We do it all the time here. A great get-away for watching the football games - The grand kids have a blast when sleeping over night... We sleep-over in it ourselves as well...
I only have the Electric hooked up. No water or sewer connected... That is really not so much a problem using the sewer tanks - you can use one of those 12VDC macerator type pumps and pump the sewer to the house septic system very easy.
Kinda of expensive during the winter months keeping the heat going. Goes thru propane like crazy - we normally just have a couple of electric heaters going on half power.
I do the same thing with my OFF-ROAD POPUP trailer as well... Always doing mods on it and playing with battery banks etc - It runs just fine connected to the garage 20AMP service receptacle again watching what you have ON at the same time.
