The Redwoods & Rushmore were built in the same assembly plant & both were born approximately the same time.
The Redwood line was under the control of the former management of Carriage & his plan was to be the new luxury line of 5th wheels replacing Carriages, but after just a couple years, management differences got in the way I believe. He went to work for Heartland division & the Landmark 365 was his design that was the plan he had for the Redwoods.
The Rushmore was under Crossroads management & was to be #2 in their line up following the RW, but for some reason or another, quality control or management, it had a very short lifespan.
In '15 or '16, if I recall, Crossroads division was put under the management of Keystone cutting management positions in half.
