I've already pointed out to you in another thread, that airbags, spring helpers, tires, "fancy" hitches, will do nothing to increase your towing capacity or payload. They might soften the ride, reduce the sway, make the TV and 5th wheel sit more level, but that is about it.
Do you want to get "down the road easier" or down the road "safely and easier"?

Look at the sticker on the door of your TV as well as the toy hauler and give us some numbers to work on. Never mind about the dry weight of the toy hauler - it isn't important.

You really need to take the truck - complete with any passengers and any other cargo that you usually put in the truck or in the bed - to a weigh scale and obtain some real weight numbers. Don't forget to add in the weight of hitch to these figures.
