I use the Dometic supplied with the Scamp
. Because it is new and still serviceable I will not buy a new one yet. But I can tell you that every time I've gone to unscrew the large cap where the "pee" contents come out, I've scraped the skin off my thumb with generous bleeding. The cap is too close to the carrying handle and I think this is why this happens to me.
I did a drawer slide out mod this summer using leftover cedar ply I had from closet shelves, furniture glides on bottom and a cabinet drawer handle. I love it and did post here on site. Not fancy but works like a charm.
Since in 5'2" the height isn't a problem for me, but I bet it would be for taller folks. Have never noticed any odor and use for about 2 nights and half of a new day before emptying, but only #1.
I will buy a thetford when this one crumps.
