Keeping My 2001 LXi Warm in Winter

[Urnie-Medie]

Just getting back from another trip. Still having trouble keeping the coach comfortable. Below are a few things I noticed:
1- I know this sounds crazy but when I turn the coach right on the highway I get a blast of cold air. Not when I turn left.
2- The blowers on the Aqua Heat seem to be low - will take of the covers and inspect.
3- The electric heaters seem to be noisy and slow - does anyone have a good replacement?
4- On the trip I hooked up some free standing electric heaters just to keep a little more comfortable.

I have to believe there is definitely a problem - I will just keep Looking.

I have tried to use Mike's suggestions.
