the SUV's you mention are all good
because you need to stay with a short wheelbase SUV you will be happier towing a shorter trailer.
trailer tongue weight is the remedy for sway issues .
none of those SUV's have extra capacity to spare if you experience sway with your new longer trailer.
how about keeping your current trailer and change the way you camp ?
assuming you want to sleep 4 inside then you could move your cooking and dishwaswhing chores outside.
buy yourself a 12 x 12 EZ-UP Quik-Shade and use a coleman stove or a combo stove / grill setup .
carry some dishwash tubs .
Low SUV is a mercedes 4 matic sedan . the second one we have owned .
i buy them because they are really good cars , not because of snooty status .
mercedes are VERY quiet , ride really well , handle very well , brake really well and the 4matic goes in the snow in the mighty Cascade Mountain range we live next to .
the rumour about high maintenance costs have not happened to me .
if i did not own a duramax i would own an ML 350 or a BlueTec ML.
hence the term "LOW SUV "
