Hello new to the sight and just started full time rving in eastern Colorado.  Been at it for a month now due to some family issues and some problems of my own. I have a 2010 rockwood ultra lite 30' trailer, bumper pull. Its like brand new as it has sat for a few years but got a good deal on it. Everything works mechanically, I did have to fix a lot of leaks (water) but got those done and everything seems to be good now.  It is supposed to have tank heaters it has a switch in bathroom for it just not sure what I'm looking for if they are actually there and if they work.  Any suggestions?  Happy camping!

Welcome to the Forum.  

Most tank heaters are simply flat heating mats attached to the tanks.  Without turning them on and getting under the rig to put your hand on them, I don't know how to tell they are working.  The best bet is camp where they won't be necessary.  :)

We have tank heaters, and we had an RV tech check them when the underbelly was down during a repair, but I have no idea if they still work.

Happy traveling.
