I have a popup but was looking for something that I could take to deer camp so I could still tow a trailer with the trail bikes. Right now deer camp is a 10x13 canvas tent and a large tarp.

 

Bigger trailer, set the camper on it, and have room at the back for the bikes. Prolly still need a smaller camper, though.....

 

Without knowing anything about the Travel Queen brand, I can tell you that 10ft is as big as my Sun Line, which makes my 1-ton sag down about an inch or two - I have 6 leafs in my main packs and 2 in the overloads (so way more springs than your halfton) and even with the camper empty the overloads are just touching their pads. Based on this I think a camper of that size will be too large for a halfton truck, even if you beef up the springs and add a nice swaybar I'd be concerned about the rear axle as its bearings are rather small (compared to those of full-floater Sterling axle in a 3/4-ton or a 1-ton truck).
