Dolly : As long as you don't mind to maintain a dolly that’s fine.
Brakes, tires, wheel bearings, registration, inspection , storing the dolly at home as well as a campsite. Some find it too much to do.
OP, as said depending on the toad , the 7 way plug has to be wired by you. You are adding an empty plug for your lights. Add a charge line besides the toad lights if necessary.
In addition to the 7 way plug :
Depending on the toad make/model, you might need a lighting harness in order for the lights to function as normal.
I skipped that step and drilled a hole in the taillight housing for my own rear lights, a socket and bulb. No harness needed.
Not a big deal to do either way. The mechanic that did my setup said it was easier and less time to socket and bulb it. However, that ‘only’ offers you rear lights on the toad, running, brake and directionals. No side marker or license plate lights.
For that , i just turn the toad parking lights on.
That’s another reason for a charge line installed on that toads 7 way plug. Make sure you use a fuse where needed.
