Take that camper to a scale and see what the axle weights are.
In any event if it does not have the upgrade to the larger front air bags you are a prime candidate for them. Chances are they are original and are ready for replacement anyway. Do you have prior service data? Also an upgrade to Koni shocks and you can get them from Prevo parts Elgin, Ill.
When we got ours front shocks were bad and I do not recall ever bottoming out.
Ride height is measured directly behind the front wheel-well at the bottom of the bay door to the ground. I do not know what that measurement is on an H-3 but I'm sure someone will chime in here.
