You might want to look at  the K-Z coyote. we have put over 9000 miles each
summer for 3 years on ours with no problems other than bending a rear jack
in a pothole.   We have owned it 4 years but only used it for travel the
last 3.  We teach so we live in it for 2 months each summer and love it.
Have driven the whole east coat and across the Rockies with not a hiccup.
Watch out for some hybrids though I have heard of some models whose
blackwater drain is so low it hard to dump them.  The Coyote sits up nice
and high.  Fully loaded except for water tank it weighs 4400lb.  and we
really cram a lot of stuff in it for a 2 month trip everything from Dutch
ovens to piles of heavy books.
One thing to note about a hybrid in very cold weather you may have
condensation on the inside of the fabric just like a popup.  However you
have a huge amount of living space compared to a standard hardside trailer
since floor space isn't taken up by beds.  Get a slide out if you can  it
gives you way more room.
