That is interesting. In Florida an Unlimited EC can pretty much do anything electrical and we have no special license to set a trailer.
The state law (wind code) has made mobile home installations pretty hard to do. I imagine it may have changed but there were no mobile homes that met the wind code a few years ago and that code also applied to moving an existing mobile home. The effect was if you had a mobile home, on a lot, you could stay there but you couldn't replace it or move it.
I imagine someone has found a way to make and certify a wind code mobile home by now tho.
The loophole was the "RV" but if you tried to tie it down by hard wiring the electric and hooking up water it was treated like a mobile home. Of course a lot of people cheat.
