WDH bracket attachment on 2720SL?

I purchased a Curt weight distributing hitch for my 2720SL, but I don't see how to mount the snap up brackets. In their proper location for the weight bars, the LP tanks block them from snapping up completely. If I move them further back, it appears that they will interfere with the swing arms for the front room slideout, and I no longer have a direct lift on the chains.

Is anyone else using a weight distributing hitch on their 2720SL? Where did you mount your brackets? (pictures would be nice )

I guess I should have asked this question before purchasing this hitch, but are there only certain types of WDH that work with this model?

Thanks!
