Mario, Welcome to th Heartland Family & Forum and congrats on your purchase. Regarding the TV, yes it can be replaced with a flat screen. You need to determine how much room you have then pick a TV based on that info. I think you have the same entertainment layout as mine so a 32" should fit as long as it's speakers are below the screen. I made semi-permanent mount using "L" brackets from a home depot. I'll attach a couple pictures. I'm not sure what you mean about the sewer compartment design. If you're talking about the hose storage, you are right. I quit using that little area and store all of my sewer hoses, fittings etc in a tote. The pulls for the dump valves are easy enough to get to. In the newer models they were moved into the docking center. As for backing up. Practice, practice, practice. Be careful not to jack knife and cause any damage. The awning sounds like it may be out of adjustment. One side may have the tension too tight. I don't have slide toppers so maybe someone else can chime in on that. I hope I've helped a bit.
