Very interesting, so you're recommending the avoidance due to weight or poor construction?

Reason I ask, is I was considering a used AMG h/e but this one had a larger capacity.

The 2" thick one should weigh less (slightly) but also holds only 54% of the fluid...

I know Rob's is the biggest and best h/e out there, but it's a bit 'spensive... my mod budget is limited until Kim and I get moved/settled into our new house.
