I am really new to the fullsize and older model 4x4. I need some ideas for why I am smelling this. I have had a flush and fill, the hose are good, no leaks. Why else could I be smelling this? Question #2-Is there any cheap way to brighten up the instrument cluster? All I have now is a faint orange glow. Also, I seen a pic of a cool fastback style soft top. Who has this, how much did it cost? Does it render the back seat inusable? Thank you all for being here.
