Anyone install Timbrens on the rear axle? If so, did it make any difference? I've had Timbrens on all my trucks with good success. First Class A and wondering if they would help with leaning when g...

When making chassis mods in search of improving the handling or ride comfort prioritize your list of potential add on items by cost. Start with the least expensive then take a bit time driving in different conditions to evaluate any change before moving to the next. When requesting feedback from other owners consider what might be an acceptable ride or improvement to one owner is not to another.
I have an older 18K chassis (2006) and so far the lowest cost changes made the greatest improvement. Correct tire pressure, weight distribution, replacement rear sway bar bushings and the cheap handling fix (aka CHF). A higher cost addition that helped was a rear track bar and Koni shocks. The most expensive addition with the least improvement was airbags at each axle. The airbags are helpful to regaining ride height after loading but did little for ride comfort other than maybe suspension bottoming. Get the air pressure too high and the coach will get pretty bouncy.
As far as which chassis your coach is built on a physical inspection is the ultimate answer to the question. Builder specs will change without notice even in the middle of a production cycle. Easy to tell between the the 18K and 20K by the rear axle differential cover. 18K with the lighter axle will have a bolt on rear cover while on the 20K the cover is welded.
