Welcome to RV.net
You have a choice between the Torklift, Happie jack and stake pocket tie downs.
We put the Torklift tie downs on ours because they bolt directly to the frame using existing holes in the front and if you have an Oem hitch they slid into the cross tube.
When you take the camper off you un pin the extensions for the mounts and nothing sticks out from the mounts.
You can shop around for the best price. If you go with just the turnbuckles for fastening it is cheaper but there are folks on here that love their Fastguns.
You need to search this web site and also do a google search for tiedowns. Torklift has instructions for installing them on their website so you can see if you want to install them yourself. It really is easy.
Our truck beds aren't strong enough for the stake bed tiedowns. IMHO
