I’m the rookie and we are still waiting on our TT order. So I’ve been watching a lot of RV YouTube— a LOT! I’m sure some of that will be counterproductive. But one video had a young couple living off grid describing their modifications. She mentioned that many RV’s have the same locks. She mentioned the key number. So they replaced all their outside locks with something tumblers? She also mentioned they replaced their door lock with a keyless entry.They liked it but didn’t love it like their other mods. Is this important to replace the locks? If so, what brand for the outside locks? And if you added a keyless entry, and you love it, what brand did you order? Thank you again!
