Ok folks I went camping this weekend and pulled our new camper (not new but new to us) It is 24.5 feet long and we got about 8-MPG. I want to increase this as much as I can for a reasonable price. I was thinking about a new dual exhaust (it still has the original stock one on it now) a set of headers and also a new cold air intake. Also should I go with a CAI or just a round large area element with a s bend bolt? I know that the CAI will or should make more power but will either help with milage. More power is good too.

Now I would like some suggestions on some parts. I was thinking about this CAI setup on ebay: http://cgi.ebay.com/ebaymotors/97-01...QQcmdZViewItem

I was also thinking about these headers:
