5.0 The Annex you didn't know you needed

RTT Annex. I didnt know how much I needed it! It's awesome to have a place to stand and change, or to stash gear. I like how it does not interfere with my 3/4 awning, and is a super easy item to install.

3.0 Zipper design

Finally got the chance to take this out last weekend. It's nice for what it is and provides a suitable area to change that is much nicer than the tent itself. The only downside I see is the install of it each time. The Gen 2 is meant to zip but I found that where the zipper is shared between the annex and cover, the zipper works opposite for each of them. One requires the zipper on one end of the aluminum while the other requires it on the opposite end. Not sure why it was designed this way. Instead of just being able to zip it to the strip, it needs removed and spun around each time you install/remove for the other piece. So far that's my only complaint.

4.0 Gen 2 annex

the zippers are very sticky sometimes but once its set up its a dream

Question & Answers

5 Answered questions

Q: do you have to take the travel cover off to install the annex ? Answer this question

A: Yes, the zipper used to close the travel cover is used to attach the annex to the bottom of the tent frame. The annex cannot be attached until the tent is open. 

Answered by Mas80 from Nashville on 10/27/2021

A: Yes. You need to unfold the tent too.

Q: Does this come with some sort of storage bag when not attached to the tent? Something to put it in when traveling? Since this zips up where the cover is attached, it doesn't seem like it would be folded up with the rest of the tent. Answer this question

A: Yes it comes with a carrying bag with handles for easy transport.

Q: What are the dimensions of the base of this annex? Trying to determine if someone can comfortably sleep in this area. Answer this question

A: I have the annex for the standard size tent D it's very spacious. Could easily fit a queen air mattress in there. Plenty of room. 

Answered by BigBen88 from Hershey, PA on 03/29/2021

A: Not sure on the exact dimensions but its wider than the base of the bottom of the roof top tent. You can for sure fit 2 cots in the annex. 

Answered by Clay on 03/29/2021

Q: Hi! Can the annex be put around the ladder so that the ladder is safely inside of it Thanks!  Answer this question

A: There are tents that allow the ladder to be in the annex while still being able to get in the tent. That’s why I was asking. 

Answered by JRod from White Plains, NY on 01/10/2021

A: The ladder is on the outside of the 2588 so you can still go into your tent.
