You will need to play with pressure settings in both tires and airbags when you get them. We bought 1 year old winnebago aspect (class B+/C) and when we left to come home it had terrible handling (about 400+ miles worth). Tire shop would not put air in rear airbags and could not check inflate rear inners! Yes this was a major tire store! Anyhow got home and check and rear airbags were basically empty, tires were set to high psi reading except for inners. I have had airbags on several vehicles and have had to play with them all. Found that the front on rv need to run 55-60 and rears 65-75, airbags 55-60. Running OEM shocks (have new monroes but havent been able to install to high heat temps over summer). Anyhow as noted above the 80psi max is way too high for most for a good ride/handling. There was a magazine road test on the winnebago some years back and they were harsh on the handling but I cannot locate a copy of it anywhere.
we run a light load with max weight around 14K, do not run full water tank (about 1/3d) and keep black/grey drained. So it will be up to you to experiment and Yes I do recommend airbags if none installed.
posted another item but it has not been posted to the board. Happens often it seems. Anyhow if you do install airbags go for adding a built in compressor so you dont have to crawl around to add air and can also do on the fly to further help with your efforts. Stabilizer bars may help but really are not the cure all IMO.
