No it is not. The 1x1 piece of wood, even sandwiched between the siding is definitely not design to hold thousands of lb weight.
I removed plywood I had for couple of seasons as a shim under my big camper and clear imprints show that the camper weigh applies to front 6" and rear 6". This is where you have reinforcements.
Center of floor will bend under 200 lb foot. Maybe not to degree to notice it, but you might try it when you have your camper on jacks.
