I was stopped in Atl. in 2005 while riding the hov lane in my MH. I was pulling a car trailer with my vette and BMW bike on it. Officer that stopped me said he did so because I was the only one he saw in the coach. I told him I thought I was legal because motorcycles and bus's were allowed and My wife stuck her head out and asked him if he would like a cold drink.
He just chuckled a little took a coke and sent me on my way. What they would do today I have no idea but I still travel hov when my wife is with me.
