We had a 2006 Springdale 249rls and we went from a camper to the short 5th wheel so we could tow our boat behind it. I had a hitch custom fabricated and welded and bolted to the frame. It preformed well and I did not have any issues. Another waterski buddy still has his Springdale and double tows with his trailer every summer. I would just make sure your brakes are working well on both vehicles.
We enjoyed the roominess of the trailer and it served us well. It was not a high end model so there was some repairs and additions that I had to do but it did what I wanted it to do. I say go for it.
