While driving on I 40 today we were getting waved and pointed at our 2015 Cardinal 3450RL. We were hoping it was because our bird is so pretty, but it was actually because we were dragging our fresh water tank on the ground behind us, along with the coroplast. Pulled over and called Good Sam Roadside Assistance. By the time twenty minutes had passed for the guy to try and locate us, my husband had removed the damaged tank and other parts, so I cancelled the request (GS Roadside Assistance is another story). We are taking her in for paint work anyway, so we will get it fixed then. We did have some water in the tank and drove the ridiculous 40 with it's rough bumps, but it looks like the factory used the minimum amount of framework to hold the tank in. Thankfully, it jammed itself between the frame and did not hurl itself onto any vehicles behind us, nor were we hurt trying to get the tank out with crazy traffic zooming by us. Might want to have your tanks checked, if possible.
