I dont have an answer for you but I would have someone wall (jump) around in the RV while I was under it trying to pinpoint the noise. I would also spray anything that looks like it might need lube or make noise with dry lube. Or a maybe wet lube (to get into tight places) then wipe off the excess so it dont attract dust.
