cougar high country 2013

I have a 2013 Cougar High Country and my screendoor plastic is all cracked up. Not the slider part with the handle but the stationary side. is there a part number on where to order replacement? or is it that I have to replace the whole door?

Is it OK to go from a load range D to a load range E ? Tire size will be the same and will be using same wheel. Thanks .

I need to change out the tires on my rig. Which jack is best for lifting one side just enough to take 2 tires to replace at a time? Can't take trailer in so I have to take tires wheels myself. Thanks for tour time. It's a 2013 cougar high country 329 res.

Is there a bulb (L.E.D) to replace the front flood light and the porch light? The cover for my porch light is orange but would like to change it to white for brighter look. Anyone have any suggestions. Thanks .

In our Cougar High Country the kitchen island alarms keeps beeping. I believe this is the one that has to be replaced every 5 or 6 yrs. Can I purchase it anywhere or do I have to order it from our dealership?

Had a gust of wind bend one of my awning arms to a weird angle. Luckily we were able to close it before further damage. Due to awkward bend the bent arm forward arm doesn't close all the way. Stays open about an inch and a half.
