Thank you all for the advice. At this point based on most if not all of you who said to correct the problem and don't depend on a sway system device. I will definately put the trailer on a scale and check the tongue weight related to the trailer weight before scrapping the idea.
I had a toy hauler but wasn't roomy for long stays. Toy haulers in most part are designed to haul toys with no slides or small ones. Since my problem I did start looking again and did fine a outback made in 2013 and 2014 that has large living area slide and a queen bed slide out. My problem is not wanting to buy a new one and can't find used ones. Maybe a couple years down the road there will be some used ones available.
