Help 2020 thor vegas - does anyone recommend these?

Hi I read this on one of the THOR forums: If needed who does this and what is the estimated cost? Thanks team!!!

Any motorhome over 25 feet on a van chassis is going to be too much for the stock suspension and it will need upgraded sway bars, steering stabilizer and Sumo Springs to get it to ride and handle properly.

Can you imagine how many thousands, 10s of thousands, hundreds of thousands??? motorhomes are driving around this country without any of those aftermarket modifications? With no issues?

That really is a personal preference and not a hard and fast rule.

How do you like the way your coach drives? Does it feel like its being pushed all over the road? Does it ride like a wet noodle? Do you want it better, if so how?

Each suspension part/enhancement does a specific thing and addresses a specific issue. First you have to figure out what do you want to address?

For our coach: I did an alignment and put Sumo Springs on the front. I've been happy with that. The Sumos reduced the lean in turns and some of the "wallowing" that I thought the front was doing.

Theoretically speaking, the Thor Axis/Vegas should have pretty good linear stability with its 188" wheelbase. That is 18" longer than Mercedes Sprinter based coaches.

For example both the Ford based Class A Axis/Vegas and the Sprinter based Class Cs are about the same length- 25.5' or 306". The Axis/Vegas has a wheelbase to length ratio of .61 and the Sprinter based coaches have a ratio of .56. Anything over 0.6 generally has good stability.

It is my understanding that Ford upgraded the front sway bar in 2021 along with the new engine which is reported to make stability even better.
