ktmrfs, I agree with you on the value of "backstab" electrical outlets. Letting the RV industry get by with "rube goldberg" wiring is a shame. Any outlet installed without a box is a hazard but every RV out there has outlets with those backstab outlets. Even wires secured under screws can become a problem when stressed (not to mention the problems of aluminum wires). The area making contact in the backstab outlets is nothing compared to wires secured by screws - they're asking for problems using them. Good job replacing yours with the real thing in boxes!
