What are these air valves for?

[prayers1]

I recently purchased 1998 34' model, so everything is new to me and learning more as I go. I guess the PO tried to explain everything that he knew and I'm thinking he didn't really know that much. I did ask about stabilzers and he said none.

What I discovered under the front air dam are 2 bicycle valves about 1.5' apart, there is a blue line that runs from each one, I haven't figured where it goes for the moment.

I'm thinking it might be used for a stabilzer system, something like air shocks on a car

If you need a picture I might be able to get one.

If I had stabilizers wouldn't there be a dash light or a gauge telling me status or how much air.

most likely after market air bags for suspension, probably firestone. look on front axel and there should be one on each side. The valves to keep them inflated to correct psi, most I believe are 90psi. Might need to verify that. Good luck.
