I bought one recently just before heading off on a little adventure up in western Canada. Never even took it out of its bag to read the instructions - just put it in the trailer for "just-in-case".
Well "just-in-case" came a couple days later. I was heading towards Ft Nelson, and a rear U-Joint started to go bad (still kicking myself for not carrying a spare). Got into town, and the local NAPA had closed about 30 minutes prior to my arrival. On a Saturday night. And they didn't open till Monday morning. Oh - rain and snow was predicted (this is the middle of August!). The temp was dropping outside. So I quickly went to a close-by campground (
http://www.tripleghideaway.com/ - they're awesome) to "camp-out" till Monday morning when I could get a U-Joint for the Jeep to keep going.
First picture is my usual set-up with the RTT (which is really a double-sized Tent-Cot from Cabela's) opened up. I climb on top of the cooler to get into the tent. Notice there is no cover/protection connecting the back of the Jeep to the tent.
The second and third picture show the Slumberjack Roadhouse Tarp connecting the Jeep to the tent. It was a lifesaver (ok; that's an exaggeration - it just made life a whole lot nicer the next few days). I was able to cook on the tailgate (doesn't everyone's Jeep tailgate drop down flat?), and work on the driveshaft on the tailgate without being exposed to the rain and snow. And I could go back-and-forth between the tent and Jeep without getting rained on, get stuff out from the back of the Jeep and stay dry, etc..
I quickly set up camp at the Triple G (got the tent opened up and what I needed out of the trailer), and then literally pulled the Roadhouse Tarp out of the bag for the first time that evening and got it set-up. It was pretty straight forward, and the stakes were quite beefy and the provided rope was plenty sturdy. Not bad for my first attempt - I was trying to beat the rain & snow - I wasn't trying to be pretty. I was quite pleased with how it turned-out.
It has plenty of options for setting up. I made it work for my situation. It didn't take long to set-up (especially for my first time figuring out how to attach the straps and buckles to the back of the Jeep), and literally once I got the final stake in the ground, it started raining (and snowing later that night). I was/am extremely pleased with it. It will always have a place in my lil' adventure trailer. I strongly recommend getting one if you think you'd ever need such a thing.
The only issue I have with the tarp (if I had to name one) is that it is not exactly a perfect rectangle (that's part of what makes it so cool). And I don't want it to be a perfect rectangle. It just makes it a little difficult to fold-up and roll back-up into the provided sack. I got it done, and got everything back into the provided storage sack with no real issues (other than it was still wet). Fortunately the storage sack is a little loose (a good thing) so it doesn't have to be perfect. When I got home I pulled it out, let it dry, and then repacked it.
It is also a little bit of a heavy package. The metal poles (it comes with two - I just used one on this occasion) are very strong and study, but they're not light. Weight isn't really an issue for me, but just so you know.
