That is awesome to hear Andy!!
As for what I might do to the second one I just ordered.... hmmmm...
Well, the very first thing I am going to do is slap some single side cf tape onto the bathtub floor corners. As Ron noted they need to be sealed up some way, and this just seems the best way to go about it.
As for modifying it to have a higher bathtub floor, uggh, that could be really hard. The more I look at mine and try to figure out how to go about adding another two or three inches of cf along the top of the floor, the more I think it could be a bit hard to do. Seems like it would be much easier on the manufacturing end, but with the bug netting already attacked pretty much all the way around it, it could be a nightmare for whoever I would hand off that task too. Still though, as I mentioned in my review of the SMDSX, I would love to see another two or three inches. It should be totally unnecessary for rainspray, but for setting it down in a really wet grass lands, or muddy area, it could save us having to take a secondary ground cover.
I am also going to look at having a short zipper attached to the non-door-side netting, probably around 8 - 10 inches long, so I can at least make that side of the "vestibule" actually usable. It would add around 3.4 grams (0.119 ounces) and to me that is justifiable weight.
Whoever I get to do that zipper mode, I will probably have them do the "Loops on the outside of the bathtub side-wall where your head is at." option I mention in my review. Thinking of just using some 3/16" flat cord to make one loop on each side. Should add around 1 gram, maybe 1.5 grams of weight for them. Going to probably make them large enough to hold some wood sticks I can pick up off the ground. This is such a minor problem that it is not worth a bunch of weight and extra stakes.
Anyway, really awesome to hear you found my articles useful!!
I am hoping my second one will be here in time for a trip to Mount Lassen that I got invited to go on next week, so I can break it in all nice and proper!!
