IMO, it should not be considered "normal" for air to get under the linoleum and lift it on any RV - popup, TT, 5er or MH. Nor should there be enough vacuum created while driving to lift it.
I understand the need for expansion and contraction but you'd think as a minimum it should be glued at all penetrations and along the slideout. Those are the only places you'd expect to potentially have air flowing in.
