Roll off.... Where's my fellow trailer/wiggle wagon drivers

Seems like everyone likes talking about boxes and flats on this site , just wondering if anyone else had had the excitement of pulling a "pup " trailer behind their roll off, I don't pull one every day but have quite often when I'm in a day cab , when I'm in a sleeper I pull a 48' spread dragon double can when I'm not hooked to my frameless, just curious and trying to start a friendly thread about pulling obscure types of equipment

also has anyone ever pulled one of these new frameless roll off trailers ? Trying to talk to the boss into Atleast demoing one to see how they work for us as my Tare is 44,500 with one can on and pushing 50 with 2., thanks
