I would consider that TT a Park Model. I did a bit of internet searching and it does have holding tanks. A true "Park Model" will not have holding tanks, and the toilet will be a residential toilet and plumbing is directly to a sewer.
Your Salem has an RV toilet, and holding tanks, so I think I would call this a "cross-over park model!" :)
From my experiences, the difference between park models and an Travel Trailer:
Park Model has:
Sliding patio door
Residential refrigerator
Residential style toilet
No holding tanks
Real furniture (or stand alone furniture ... not built in ... like Dinettes).
Your's has a mix of both, basically a regular Travel Trailer with the Sliding door. I would still put this with "Park Model" though.
Salem is a good brand of camper. It's not a "top of the line" camper that a movie star would ever own, but Salem's are good, (Mid-range / mid-grade), depending upon the model style).
