New 2018 Sprinter/PleasureWay brakes feel soft and low

I have a Thor Four Winds with a Sprinter Chassis. Like you, I was surprised at how soft the break petal is. I does not seem to be a safety issue though.

When I checked the VIN of the chassis on my RV for a parts order, I learned my 2018 RV is mounted on a 2016 chassis. But that is another issue. I know, I should have run the VIN before purchase, but maybe that is normal for Thor and other manufactures.
