RVing Questions

So now that I have the "shakedown cruise" out of the way. I have some questions.

The coach needs a bath. Picked up a lot of bugs and road dirt along the way.  What products have you used that you like? That you dislike? Do you use a power washer? There is a power washer in the shed, it's only been used once to clean the deck before we restained it. I think it is too powerful and will damage the coach.

Tires: What type of air compressor do you have? I have one that I have carried around in my car for many years, and used a few times, but it is very slow.  Do you use a tire monitoring system? Are you happy with it?

Engine Heat and Road Noise: This is something I will have to adjust to because I love traveling in my coach.  I normally don't use A/C, I had to run it because it would get too warm in the cab. Why don't they put an A/C vent near my feet?  Are there any after market products that can cut down on either of these problems?

Bouncing and Swaying: I understand that I am driving a powerful truck with a big box attached to it. Are there any products that can be added, such as heavy duty shocks?  If I'm driving on a smooth straight road, the ride is similar to my SUV. I will slow down if it's windy or if the road is really bumpy. Are there any products that can be installed to help with the sway in these conditions? Or am I doing something wrong?

Thanks for any information you can give me on these subjects.
