Well now Ray... Next time I open the underside... I'll Check !!
Just not a place I've visited often... Thanks for the information... My Creaks and pops... have been in lots of places... sometimes it's the floor of the BigHorn... sometimes it's ME !!
My post was only a reminder that the floors of Heartland products have evolved from what they were... to what they now are putting in... which is a sandwich with top and bottom panel and insulation between. Which I believe will be quite a bit warmer.
