Mod's on new Montana

[Ozz]

Hello everyone, second day owner here, been on the Good Sam Forum for a few years, had a Keystone Sprinter TT.
Always loved the Montana 5th wheels, Sue and I bought our '07 3400 RL, absolutely love it. I am adding a 220 Volt outlet in the washer and dryer space, we bought a Maytag set at Sears, nice S.S. tubs, 1200rpm's, Vroom, Vroom, more power!
While I am at it, and have the electrical panel dangling in the bathroom, I added a 110v outlet in the basement, right by the hole that has water lines coming into it. I made a charging station for my cordless drills, with a basket shelf for the chargers. I will add an outlet in the bathroom for a night light so my Prostate and I can visit it numerous times, when I should be getting a good night's sleep.
I bought a second rooftop A/C unit I will be installing, as well as a Stationary Satellite dome dish thing, the holding tanks will be introduced to an electronic monitoring system, said to be darn accurate, drove me crazy on the Sprinter, that monitor never read right, this looks like it's twin. I will also install the back up camera I took off the Sprinter.
I am interested in hearing from those who added a rear support shelf for a BBQ Grill, & bike racks. I would hate to remove the rear cap, but may have to, so I can access the frame, don't know.
Any tips would be appreciated, also, any suggestions to fine tune the beauty.
Hope to run into some of you, we will work on the Montana and in a few Month's head for the interstate.
Take care, Jim and Sue
