nobody, outside of who you talked to, says you can't live in your RV....just do it if it fits your life style. lots of people do it so don't let that one phone call change your mind. we like our 3402, nice unit to "live" in.
take a look at the bottom of this page from montana rv:

enjoy your travels.
