Some of the pros and cons are listed in that thread. I don't consider it an optimum combo. Because as Mac said, the bug net and shelf ( you can go under
the RL) are going to be in the way a bit. They are going to lift it up for a pretty good gap on the right side. On the left side, it will drape down right on you pretty well like a sleeping bag on the ground. Depending on what you are trying to do, the above could be a positive(lots of room) or a negative. However, the negative ( not as warm as you want on top due to right side gap) can be overcome with a light TQ, which many use with the PeaPod any way.
Definitely doable. But I like the Claytor No Net combo much better. Just lot's more room for the pod to drape onto you and more room to add extra insulation for super cold temps. Traveler would probably work great with a PeaPod, but I have not tried it.
