I need brackets that attach to the truck to secure the TC?

Torklift is a great company with good products but you may want to look at all the suspension and tire/wheel upgrades you are going to need to carry that heavy camper. When you look at what all that is going to cost you may want to just upgrade your truck before you spend money on tie downs. Torklift tie downs are not universal so if you get a newer truck you will have to get another set of tie downs. I would guess that Lance 1130 is 3000-3500lbs dry a lot of weight for a 2500.
