Towing it should be no problem as long as the tow vehicle is capable. You may not get as good MPG as they are built like a box............
....... and yes they do have the same holding tanks same as a regular travel trailer. Water tank also.....
The biggest difference I have seen is ours has a residential refrigerator (as do many TT now) and residential water heater. Our Wildwood Lodge gets towed short distances about monthly.
