Moving the trailer with an electrical trailer dolly

For the last past year or two I have had to move the trailer with the electrical trailer dolly. I have to move it every 30 days according to the city I live in. SO, here's the problem I broke the "mount hitch" putting stress on it going side to side, up and down trying to get the trailer right where I want it. After I was I done moving the trailer I remembered I didn't check the tire pressure in the tires on the trailer's wheels and in the trailer dolly's wheels. Yes, I know that this was an idiotic move on my part, especially because there is a sticker near the wheels on trailer stating "Attention Driver: Check tire pressure before moving". The bottom 2 bolts went right through, and then the mount hitch came off. I temporarily put 2 washers on the bolts and it works for now. I have been looking into getting a new trailer dolly mount, but I cant not find a dealer that sells them in my area. Also, when I hook up my trailer dolly to the trailer's electrical system it works for a couple of minutes then it goes out and doesn't work. I have to hook battery clips up to the battery on the trailer to use the electrical system. Also, when I run the trailer dolly, and then finish moving the trailer I find out it caused the breaker for the side of the house's electrical system to go out. To fix it to get power back the breaker for the side of the house has to be turned off for a couple of seconds and then turned back on. I have to move the trailer again the 24 of July.
