Pop-up to TT. What do I need?

Depending on where you camp, you may want something more effective than the plastic wheel chocks. Your TT will weigh substantially more than the PUP and if you're on even the slightest slope, it will feel more stable with a good set of wheel chocks (and is less likely to roll away, in which case you have no chance of stopping it). We like the X-chocks, which fit between the wheels (they come with a detachable "wrench" that you use to adjust the chocks.

DH loves using a battery-powered drill to raise & lower the stabilizer jacks. Much easier than turning things by hand.
