No one mentioned the "W" word .... wardrobe. I had a 17Z which I dearly loved but which I lamented the lack of wardrobe / place to put your clothes. Since it was just my wife and me we kept our clothes on the other bunk, but with 4 people this should be considered. I sold my 17Z and got an RV with many wardrobes - over compensation, perhaps but now the only clothes I see are the ones I am wearing.
Based on that, I would not rule out the 19H but there is another consideration that I did not see mentioned - trailer hitch weight vs rear axle rating of the Borrego. 5000# rating means nothing if the rear axle will be overloaded. When I had my 17Z it weighed 3800# with 600# on the hitch, and these were weighed weights on a CAT scale.
OP - do the math and if it looks like it will work out based on say 4000# with say 600# on the tongue then get the 19H. You had a popup before so you should have an idea of how much stuff you would carry. Take it from there.
