Is Jungle Tank a thing?

I'm just getting back into playing again and I'm trying to find some basic viable strategies that suit my playstyle. I like playing tanky champs, and are two of my favorites. I know neither is really a dominant pick, but I mostly just play normals and would rather pick a champ I find fun to play. I always found I could clear jungle pretty well with cho's aoe and his built in sustain, but now...not so much. I tried 9/21 at first for a full on tank build and going gromp-blue-red-krugs, but found I could barely clear the krugs camp, and that only if I juggled them with rupture and leashing. Then I tried 21/9 thinking more offense would = faster clears and less health lost, but that ended up being even worse and I had to b right after red.

So...is jungle just that much harder now, or do I just need to pick a new champ?
