We picked our Ollie Mar 3 2018 Hull #330. After the walk around we headed for our first nite of camping in our new Ollie paid for by Oliver. We were all excited. After getting set up & leveled up, I attempted to deploy the carefree awning. The foot on the support arm closest to the hitch wouldn’t go in the attachment that holds the support arm to the trailer. I thought I was doing something wrong but after careful evaluation, I measured the foot & it wasn’t going in. It was too big. Luckily I had a hacksaw & cut off a piece to make it fit. So far so good. That evening before retireing I attempted to stow the awning. The support arm wouldn’t go back in its stowed position. It wouldn’t slide down the grooves provided to get it in the stowed position. After looking at it I realized it had come out of the grooves it’s suppose to slide in. Try as I did I couldn’t get it in the stowed position. I retracted the awning as far as it would go & left the support arm hanging. Next morning, I tackled the problem again. I realized the support arm wasn’t going into the stowed position with out some help. I took a large screwdriver & pryed the rail far enough apart to get it back in the track. Even then it was difficult to get it in the stowed position. This experience convinced me the carefree awning was poorly made & just a piece of junk. A few days later preparing to leave the camp ground, I went to the dump station. Dumped my black water tank & them my gray water tank. Flushed the black water tank & closed the valves. We proceeded to the next camp ground and stayed for a few days. Again went to dump & realized the sewer hose was full of waste water. I put the hose in the sewer drain & took the cap off the end of the hose. Let the tanks drain & then started to figure out what was wrong. I realized the gray water valve was closed but the black water valve was still open & it wouldn’t close. I was extremely disappointed in this Oliver ELITE travel trailer. Since we have found numerous small annoying things wrong with our trailer that should have never been allowed out of the factory. I attribute it to poor quality control.
