Removing the A/C

 I would say that even if someone towed unsafely or not, you can be sued regardless. Being faultless in an accident does not mean you can't be successfully sued for having done nothing wrong. Believe it.

After speaking with multiple dealers & learning that each unit is weighed at the factory and labeled - and there is no way to guarantee the weight, even when special ordering - we've opted not to proceed with an R-Pod at this juncture. I would have been very upset if we ordered one sans A/C, M/W, etc and it still ended up weighing >2400#.
I can't understand how there is such great variability between the same unit floor plan with the same options, or how they get away with advertising some as 2137#... What happened to quality control?
Maybe someday.
Thank you to all who replied.

Just for the liability reasons, you made the right choice.  Once you add your stuff you can add hundreds of pounds more.  My rule of thumb is stuff + full water tank will approach an extra 1000 pounds, so a 171 fully loaded will be pushing the limits of the 3500 pound towing limit that you find on minivans.  Which is why we usually suggest a 5000 pound limit, minimum.

I would like to thank this group for being kind and thoughtful.  I did not get a sense of meanness that can be so pervasive in internet dialogues.  Kudos to all!!
