Anyone with Experience with Shower Bunk / Bathroom Drom Addon

Thanks to all those of you who have replied to the original post. I am not in trucking yet but hope to take the plunge this winter. I also know that trucking is a "life style" unto itself and part of that is issues like cooking , going to the bathroom in the middle of the night and keeping cool in the summer while sleeping.

I have looked at ICT, ARI and Bolt sleepers and the truckpaper and get a bit of sticker shock looking at them (say compared to a similar truck with an 80" sleep). While I would like to get something like that eventually, a stop gap measure for me would be the bunk shower.

I have a lot of experience in RV's and camping in some very in climate places and know that I sleep much better when I have had an even a 30 second shower. And getting sleep at the right time is of course hard enough in trucking. I also hope to go into flatbed which would make a shower bunk even more valuable to me. And of course the idea of having to choose between peeing in a bottle or walking into the truck stop in the middle of the night is not very appealing ether. Also, as I hope to go OO eventually, I want to purchase fuel at where ever I can get it cheapest, not where they are offering a free shower with $300 purchase. Finally, I hope to park overnight in area's other than truck stops (rest areas, Walmarts, etc) and having a shower bunk would help. So if I can do a add a shower bunk to my first truck for 4 figures or less I will probably do it. If it is much more than that then plan B. I am still a bit worried about the winterization and related issue's.

So I learned from your reply's that large ICT sleepers can pull flatbed and oversize which is very helpful (ht @blairandgretchen). Also learned that there are add-ons bathrooms for conventional sleepers, which I did not know. This does not really appeal to me since my experinence with RV's is that the "air quality" can suffer with waterless toilets.
