When I started this post, I tried not to get long winded. Someone said I should list a few of the problems I'm having. I have had the heater put in the wall like it should be, I have had the hot water line fixed that was never connected and water leaked. There were shark bite pex rings on it so it looked fine but they were not clamped down. I have had the shower pan fixed because screws were missing and some were put in crooked. I had the fantastic fax fixed because the propeller was hitting the sides.
The plumbing in the bathroom is messed up including the hot and cold faucets are backwards. Something is wrong with the water going to the hot water tank. The AC unit is bad and possibly some wiring issues.
I trusted the Colorado dealer to check everything out because I had just lost my husband and I was trying to get to my mother in Washington state. He said everything checked out fine and I said I trust you. This is also not my first truck camper. It is the third one and bought through the same Colorado dealer. That won't happen again. I'm in a very small town without an RV dealership so I have to drive elsewhere which is a problem.
Thank you everyone for your suggestions and information. You are a great help to me.
