I use a 36 qt or a 52 qt Coleman Extreme.  I do tend to lose a couple of degrees during the mash, but I don't worry about it.

I figured it was normal and I used to lose a few degrees with my round 20qt Rubbermaid cooler, but I'm still losing a few degrees with this one...kind of frustrating, but I guess I'll forget about it.

I have a rectangular BLUE rubbermaid 50qt cooler and I usually will lose 2-3 degrees in the hour mash.  That doesn't bother me and it seems to be the norm when mashing with a cooler.

As for cleaning, it was a little more difficult to clean when I was brewing in my kitchen.  Brewing in the garage has made cleanup very easy.  After dumping the grains and spraying out with a garden hose, I use the cooler to collect the initial hot water runnings from my chiller when chilling the wort.  I then throw in some Oxiclean and use the mixture in the cooler to clean off other brewing equipment.  When I'm finished, I dump the cooler, spray it out and dry it.  Keeps the cooler clean and bright white!

Maybe I should spray paint my orange cooler blue, haha.

I found a 120 qt igloo rectangle cooler on amazon for around $60, earlier this year when I went to bigger batches.  I made a PVC manifold for it.  Before that I used a 48 qt coleman that I found for $20.

Could one do a reverse Hochkurz step mash starting at 158F and letting it drop to 145? Does it matter if the Beta rest is before the Alpha rest? Or vice versa?
Anyway, I do have a fair amount of head space in my cooler (36qt Coleman Xtreme) since I'm doing 4 gallon batches. The last batch I did, I mashed at 152F for 90 minutes and at the end of the mash it was at 147F. Oh well.

If you hold the 158 for any length of time, you will denature the enzymes that work at lower temps.

Ah, I see. Well, that's cool I guess. A Hochkurz step infusion is easy enough.

I just purchased the new version of the 70qt Coleman Xtreme. The drain seems a bit higher than before and the channel is not as long either. Long story short, bulkhead + bazooka tube does not work as well as before.

I am not giving up the bulk head as I enjoy being able to close the valve with one hand. I am now thinking 3/8" barb inside with a bit of tubing and a hose braid.

Overall i like the dimensions of the new version better. It is a bit shorter in length and a bit deeper. Walmart still sells the older version online.
