Storage

We've been eyeballing TM's for the last 5 years since we saw one at a campground on the NC Outer Banks. Purchase is in the future but not here yet. We have a Coleman popup currently.

Question: Where do you guys store dirty "outside" items like a water hose, wheel blocks, tools, extension cord....? I have a storage bin on the tongue of the popup where I throw this stuff. I don't see anything like that on the TM.

Question 2: Can items be hauled on the top with a rack? Or maybe the question should be can a rack be installed? We have a sea kayak we carry on the popup.

Thanks!!
