It's not rocket science. If you don't already know what to do with your feet (and you should!), you will after the tailwheel transition.
One of my first checkouts, post-PPL many years ago, was in the Citabria during a basic aerobatics course. This was right before the endorsement requirement was added to the rulebook, so I was grandfathered in on the tailwheel front. Years later (having continued to fly the Citabria/Decathlon series), I had no trouble training in the -6 with Mike Seager or flying my -8.
After a fair number of hours flying and teaching in larger, more powerful tailwheel airplanes (chiefly the T-6) over the years, I can assure you that the RVs are creampuffs with no bad habits. Give it a try; you'll love it!
