You will need to be more specific on your TV, camper, trailer etc.. before anyone here can really offer you advice. All you're telling us is that your rig tows/hauls bad and you need help.
DO you have a DRW or SRW? What is the model of the camper? What is the weight of the camper. What is your payload of your truck? What kind of horse trailer and how much does it weigh? How are the tires? How fast are you driving?
There is literally hundreds of years experience in RV'ing on this forum but there are not any mind readers that I am aware of.
