Early 2014 Spree Connects had a BAL frame. These are very good frames. KZ later went back to Lippert's frame made from 3 pieces of 1/8" mild steel welded together that *look* look like a regular 1-piece rolled beam. These frames flex a lot. If it's not the BAL frame, I would inspect the frame carefully, especially around the spring hangers as they have been known to develop cracks there. In 2014, Spree frames were coming out of the factory with bent spring hangers. Check to make sure they are all perfectly vertical. The 3-piece frames have enough flex in them that the aluminum framing in the superstructure can be damaged. The photo below shows a failed weld that resulted from excessive flex. The plastic bushings in suspension could have failed - ours did in just 2K miles. I would plan on doing a bearing inspection and repack and inspection of the brakes.
Otherwise, they have the "usual" travel trailer quality issues. I would say somewhat above average in quality. If it weren't for the sealed bids, I would highly recommend that you hire a good independent RV tech to inspect it for you. If you know little to nothing on it's history I would replace the tires. You probably will not know how they were treated and could be a candidate for a blowout.
