Welcome alfredcycle to the forum & irv2.
Here is a
Owners Guide for your coach and here is a
brochure for it.
The brochure will give you tanks sizes, weights, options etc,etc.
We have people that have them and some full time in them.
All Newmars are well
insulated and well constructed it does not have to do with any given year since I have owned them.
Here is the
recall list for that year.
This is a start others will chime in, good luck and enjoy the hunt.
