While looking at old inventory at LivinLite dealers, found a 2010 Quicksilver TC2 320 pound pop up small truck camper. We purchased our CL11 from Boat N RV. It's an interesting idea with two 70"L x 25-5/8"W bunks. It's new, just very old stock:

Good luck! Looks like a fun way to go. Never seen one of these.
I'm not buying one, but wanted everyone here to see it in case they may want one.
First time I've seen one and it looks neat!
