Thanks Nelson for your input.
Sorry if I ruffled some feathers - I didn't mean to.
These were forwarded comments from Harrison concerning his air ride system for the GMC motorhome.
I have the old bag style myself right now - but they need to be replaced.
I am neutral concerning the pros and cons of each system. In my opinion I think both systems still have room for improvement: Although Harrison's system can support the coach with the loss of one rear tire - it has it's limits and looks like use for emergency only. It does need a little more center support for a good peace of mind for that emergency situation. Thankfully, as you pointed out, this can easily be fixed. The Harrison's system routes the air lines as far away from the tires as possible and in addition has steel shields mounted to protect the air bags from damage should a tire explode. The "Q bag" - just my opinion- should be designed with more protection in both of these areas. Heavens forbid - if a tire were to explode at highway speeds and take out 1 or 2 of the air lines running right next to it.
With an air system down it no longer matters if it can support the weight of one tire or not.
This also could be fixed for those who have the Q bag system. What ever system you go with is an improved set up over stock.
Really these issues are each a matter of additional peace of mind and safety in an emergency situation.
I admire and support the efforts of all parties involved in the designing of these systems - each enable these motorhomes to stay on the road now and for generations to come.

Mark,
I think that your statement that the "Dual Bag" is unsafe is
unfounded. If one bag fails you still have over 50% with the
remaining bag that can be overinflated and possibly will enable you to
continue causally. As for the Harrison system being able to support
the coach with one bag I can attest that there have been failures due
to the under designed support structure. If you have a Harrison system
and you experience a failure and try to go on one bag be very careful
as the slightest bump or overload and that support structure WILL
bend. If you have a 23' coach and keep things light you may be OK, but
others should give serious consideration to the "Quad Bag". The extra
cost will be money saved in the long run.
BTW. There is a crutch being developed to enable those that already
have the old "Harrison" system to strengthen the support .
Also, your last statement that you can run a straight edge through the
center of the bags and the holes in the bogeys is false as the
Harrison bags are offset to allow the mounting hardware to miss the
bogey. The modification will also address this issue.
