Adel Clamps
There are many options for baggage tie downs.
You may construct your RV-10 to hold 100# of baggage and unless you are hauling sandbags or anvils, your baggage will consist of cooler box, luggage, jackets or whatever else you need for a long trip. In other words, more than likely it will be stuffed to the ceiling and nothing will have room to move around.
For the smaller items like tow bar, "remove before flight" covers, wheel chucks, canopy cover and whatever else you might bring along for short trips, heavy duty anchors are simply not needed.
I installed a number of adel clamps along the already nut plated holes just above the floor and behind the seat, bungee cords criss crossed between them and used as necessary. Very light weight, strong and perfectly adaptable to many different loading scenarios.
