Here is an example:
I had a Ford F-250 and put an Lance 8.6 TC on it,the only thing I did was ad Helwig helper springs and it drove almost as well as my dually I bought that was loaded with the so-called ad-ons.The cost was less than $200 installed..
If you keep your camper in the 8-8.6 foot length,you won't need much..Happi jack tie downs are much cheaper than the Torklift and very capable,especially on smaller TC's...Years ago they just used stake pocket tie downs for the most part..
Ad a rubber bed mat and your good to go.
To many over think what is needed to haul a TC,springs/springs and springs solves most all problems which are usually on larger heavy campers.
If you don't buy to much camper for your truck and stay at 3K-ish for a 3/4 ton,you won't need all the very expensive addons,just helper springs, such as the Helwig...
Without looking,I think you can get what you need for your truck for less than $500 maybe even $400 if you shop around.
