Has anyone tried the new spring? I wonder if this new spring rating would be to harsh in everyday driving?

Ok, so you have some miles on her.... good. I suggest gradualism. Sumos on the rear: Sumos on the front; Koni FSD's rear; OEM struts on front, OEM anti-roll bar on the rear (it's plenty good and a heavier one causes other issues).
I have SSR-338-47s on the rear of a '14 View Profile 24G. They are rated 900lbs at 50% compression. My friend wanted to improve the handling on his 18 View and ran into the same quandary. I called Super Springs and talked with the tech. Here's the answer: First, if you are going to tow a trailer that has a high tongue weight & use a hefty hitch, drawbar & sway control, consider the '54s'. (The weight is cantilevered off the end of the View, if you will, and has more effect.) If you are not going to tow OR if you are going to tow "FOUR DOWN", where the weight of the TOAD is all on it's own wheels, use the '47s'.
You don't want to make the suspension so stiff that it makes the ride and handling unbearable. My reason for adding the Sumos was to knock off almost all of the rolling around the long axis of the coach in slow speed sharp turns or exiting/crossing some swales. They also improve the handling in gusts & passing trucks. Which they do.
Although lessened, there was still some rolling/rocking in the long axis which is caused by the high center of gravity coupling with the energy in the suspension. (stiffer is not better here) The idea with the Sumos is to damp/absorb the compression/jounce energy and not transfer it to the opposite side or store it. Sumo 'air springs' do that. They will also 'stabilize' the coach when parked.
The final solution was to add Koni FSD 'red color' shocks #8805-1056 (not the gold, older versions). At some 15.5K miles the OEMs were past their best used date. While you can't totally eliminate the side to side rolling, you can quickly damp it and reduce it's effect with the FSD & front and rear SumoSprings. (And actually, you really don't want to make the thing so stiff that it is a miserable ride...)
