Destination TTs and Park models are catagorys that seem to be changing lately.
It used to mean no holding tanks, residential appliances and toilets, no fresh water tank or volt pump and lighting and sometimes no propane tanks. It was a large heavy house trailer that really couldn't be used as a self contained TT can for camping.
Back then there really were not any pickups capable of towing either.
Fast forward to today, and the monster diesel powered pickups with astronomical tow ratings.
It appears that the RV industry has noticed and now many of these huge trailers now are available with all the equipment of traditional TTs.
I have looked at some, and if I am in a house where I can park one, it will likely be my next one.
So one solution would be to get a TV that can handle one and you will be all set no matter what you end up doing.
