I'm obviously a biased Discovery fan, but… Beautiful rig!! Congratulations! We just got ours this summer and are enjoying it so far.
On a side note, I think it's wonderful that you're taking time to travel with your mom! Sadly, my mom passed away 2 years ago and I miss her every day! So, when I read your post, I guess I felt somewhat compelled to comment on it.
Anyway... Best of luck with the new rig, safe travels, enjoy it and the time making memories!
