First off, a 240 shell weighs what...2200lb? 5th wheel camper is more like 6 or 7 thousand.
Secondly, this isn't an issue of power, it's an issue of durability. The Accord-derived IRS suspension isn't up to 2200lb, let alone 7k. Neither is the bed-with-a-trunk-under it. Real 5th wheel hitches anchor to the frames that run beneath the beds of real trucks, which is part of what makes them so useful. And the Accord-derived CAR automatic transmission is most definitely not up to that task. Nor are the accord-derived brakes. Nor are the car/CUV tires the owner was likely running.
Nothing about the Ridgeline is in any way even remotely 5th-wheel capable.
Towing with a regular ball hitch is no better...you're anchoring to the subframe, which is not tough and merely anchors to the unibody, which is less tough.
Remember, the Ridgeline, like the Pilot, is basically an Accord. Just like the Murano is basically an Altima. If you wouldn't tow it with an Accord, you shouldn't tow it with a Ridgeline. Presence of a bed does not make a vehicle a truck (see: Subaru Brat, Holden Monaro Ute). Hell, the El Camino was more tow-worthy than the Ridgeline. At least it had frame under the bed, and V8 engine options backed with tough transmissions.
