Do you have any links to the "cracking" posts? I ask because I have read a lot of posts on theseCustomcyclegear/Mutazu/VIP tour paksand only recall one that referred to cracking and that involved a luggage rack installed, but the poster didn't provide any info on how much weight was on the rack. I'm not saying that there haven't been other similar threads; only that I don't recall seeing them.

I have taken numerous trips with my Mutazu TP and stuffed that box absolutely full with heavyweight clothing and have had zero problems, including riding in steady rain with no leakage. And I posted before that I loaned my friend this box touse on hisRK Custom when we went to Sturgis last summer onwhat turned out to be a 4,750 mile, ten day trip, and he thought it was great not only for its storage, but also because itprovided a good rider backrest for him.

But if someone has had a problem with this product, I'd like to know about it and the particulars of the use and problem.

Edit: Here's a pic of the box on my bike from July '05 just before leaving from Metro Atlanta for a trip to Toronto; I have made so many changes to the bike since then it was good to remember what it used to look like:

 

Sorry, decided to start a new thread.
Thanks..
