Hi Ray and thanks so much for your reply and the pics. I learned where more of my fuse boxes are located
Good news is that I did locate where the fuse is for the bunks. It is in the battery compartment located outside by the door. You will see an in-line 15 amp fuse just behind the chassis batteries. Take the black cover off and pull out the fuse.
Long story short, we put an egg crate mattress on top of the pad that's already on the bunks. When we raised the bunk back up, it blew the fuse. Lesson learned was if you add a more comfortable mattress pad, remember to not go all the way up and stop just short of reaching the top.
Anyway, hope you're enjoying your GT5 34H5! We really like ours so far. It rides well and has everything we need. BTW, let me know if you ever have any issues that you can't figure out. We're constantly learning new things about it. I may, or may not, be able to assist. It's always nice to have someone to bounce things off of when you have the same unit (RV).
Thanks again and wishing you the best
Jedd
