Mine are all stand alone I wouldn’t take anything like that on these days but fair play if you don’t mind doing but I don’t,many moons ago I did stuff like this and it was a ball ache for me.
When people talk about compact work this is the type of work that has to be,when I say I drive to 1 job clean it and then drive 5 or so miles to the next it’s worth it.
Thank god for google maps these days saves even driving out to quote stuff like this.
