I started looking at the Rockwood 2702SS which has a very similar floorplan. I liked the outside door to the bathroom as well as the bunks in the rear. I also was looking for a U shaped dinnette. I too was a little concerned with it riding a little low, so I looked at a LaCrosse 292BHS which also has a similar floor plan. The LaCrosse is about 2 foot higher (But also has a dry weight of about 1800 lbs more than the SV-291), it also was a little higher in price. I decided that it was too tall and was afraid of side wind and overall decrease in fuel mileage due to more wind drag. So back to the Rockwood. Then a friend bought a Surveyor and I liked it. He has no problem with it dragging. So I'm now looking at the SV291. My wife liked the 294 due to the back "playroom"/bunks for the kids, but I have the same concern as you with the 294.
The main difference with the Rockwood and the Surveyor is that the bunk beds in the Rockwood only has one double bed with a single on top. What brought me to the Surveyor is the two oversized double beds. The Rockwood has a few extra features (a little more storage, carpet in the master, skylites, outside BBQ grill, Bluetooth radio to pair with phone, the back on the U shape Dinnette goes all the way around - Notice on the Surveyor that the back doesn't cover one side so someone will have to sit there with no back). They are both at the same price point, so I think I'm going to use the Rockwood's extra features to drive down the price a little on the Surveyor because I do prefer the two oversized double beds.
