new podder

I will be ordering a 2012 171 Hood River edition in the spring.  This forum is a terrific resource for new pod owners.  I have a few questions, however.  I was wondering if anyone has had installed the heating strip that is an accessory for the A/C.  Using it with full hookups seems to be another avenue to minimize propane usage.  I realize this may not be totally adequate for winter camping but to take the chill off in the morning might be a useful addition.  In reading the many posts on this forum I have made a list of useful mods to make when we take delivery.  Also, has anyone had any concerns with the rather thin OEM mattress supplied.  I am of average weight and in looking at a 171 at a dealers, I did lie down on the mattress.  Not a lot of support.  I have heard of adding memory foam to the top of the mattress, but I wonder if it sleeps rather "hot."  The battery cutoff and a longer sewer pipe holder are on my addon list.  I have also decided to add a second LP bottle and auto transfer switch.  Not fun to run out of LP in the cool nights.  Anyway, that all for now.  Will have further questions as I continue to research.  Thanks in advance for comments or suggestions.  

Thanks for the quick response.  Will have the heat strip added.  They are not expensive and looks like they can be quite handy. 

Thanks for the welcome.  As I mentioned, I won't be taking delivery till next spring but will certainly mention how my "mods" are doing.  Reread some of the suggestions and I went crazy on anticipation of ordering our rpod.  Went to ebay and purchased some LED bulbs to replace the bulbs in the rpod.  Seems to make a lot of sense to use low power LED's and get brighter light output.  I was also thinking about replacing the jack up front with one that swivels and has a roller on it.  Might be somewhat easier to "spot" our trailer in the location that it will be stored. 

Yep.  You're right.  We had a 23' trailer years ago and had the swing up wheel and was certainly very handy.  Of coure the Rpod is much lighter but then again I'm much older.
