I am not sure which wireless product you are going with but you may want to know that on some campers its necessary to have different pressures in the two bags to assist in leveling.
No issues with my Firestone system, although it's manual-fill. Only had to replace a single air hose due to some undercarriage off-road debris, cost about $ 1.00 to fix, LOL.
Firestone is a company few generations old, Air Life is newer one. Both seems to be good, but I have Firestone suspension bags on my conversion that are well over 20 years old, so let's talk about Air Life in 20 years.
Look at the Air Life 5000 plus, as the + has an internal bumper that allows you to run with no air! This doesn't sound like a big deal, but it is one less thing to worry about.
