Make one!
I think it is a really good exercise for a new plane owner to create their own POH type document.
Things like v speeds that are not published by Vans are tested with the basics of flying skills. These also differ for every airplane no matter the model or engine combo. Mainly stall and climb speeds.
Take off and landing distances are more a pilot limitation in RV's.
Checklist are completely dependent on the aircraft. Take-off, landing and basic emergency items are all easy to do.
This gives you a great reason to get to know your aircraft and of course to fly it.
Congrats and have fun.
