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.

Question & Answers

6 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.

Answered by Lloyd from Pasadena,CA on 10/26/2021

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.

Answered by Bjj8215 from Atlanta, GA on 09/11/2021

A: Yes. It has a separate bag for storage.

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.

Answered by Kelly from 4WP Corporate Headquarters on 01/05/2021

Q: I was planning to put the 4WP $ 200 gift card, towards this annex, as it was advertised as part of the deal, when I purchased the Gen 2 tent, but it's been almost 2 months, and still no $200 gift card,or response from 4WP,as to when it might come?! ?! Answer this question

A: Seems you are out of luck. Apparently the offer of a Gift card ,is just false advertising, and no one at 4WP will make the effort to make it right. Likely best to avoid further purchases at 4 Wheel Parts f you expect honesty, courtesy, and good customer service
