No, I have not used my van with this tank in any conditions you describe.  We usually stay on the road.  Rita's not one for that much adventure !  I took pictures of mine installed today and will get them posted soon to a site where you all can see them.

I am less concerned about topes and other obstacles on paved roads than I am about boulders, roots, and holes on Forest Service, BLM, and private roads where I go into spots well beyond developed camp grounds.  So, If I am navigating such roads, I would not want to have to roll over a stone, into a hole, and bam, the tank hits the stone.  Looks like maybe two inches difference in clearance.  What do you think?  Have you used the vehicle with the tank in such circumstances?

>>        Dave, I thought the same but actually it's not a problem.  We have just spent some five months on the road with ours, Almonte to Key West to La Manzallia,  MX to Santa Cruz, CA then on to home in a few more weeks.  So far no problems hitting anything with it.  I thought the topes in Mexico would surly get ti but no, not a problem.  It's close enough to the front wheel that it follows along quite nicely.  They will become a necessity soon as most all campgrounds will require you to have a holding tank or they will not allow you in.  This IS the case in Germany now for sure as we discovered last March when we were there.

>>> I have not used it.  The photo looks like it likely reduces clearance.  Is that true?  I would like to have one, but I do not want to lose any clearance.  Also, someone else mentioned having to modify air conditioning lines.  Further information on that, anyone?  mcneely
