Scott, not to be snarky, but please explain how they're valuable. What do they tell you? Most will climb almost all the way to the replacement mark under hard driving, like hill climbing and then drop when reset. So what information is this archaic mechanical gauge telling you?
Air cleaners on diesel pushers need to be replaced every 2-3 years depending on how many miles you drive. A diesel filter should never be cleaned (blown out) and a good practice is to never remove one unless you intend to replace it.
Lastly, the OP is talking about a diesel pusher, not a pickup truck. You can't just mod the air pick up with a kit like you do on a truck. For 20 years, the air pickup systems (roof line air draw) have functioned without modification. You don't see aftermarket kits for DP's because it's not an issue.
