List Your Mods:

Good stuff. 

No AC needed here in Idaho, we can escape the heat in an 1-2 hour drive. So the used 151 pod did not have AC when we bought it last month.

I used these heat seating pads

and glued the dense pink r30 foam over them along with foil tape. They take some power so
I upgraded the battery. Luckily one of motorcycle suppliers carriers the Deka battery. So the tongue weight is now a bit more with a group 31 battery but only running one propane tank since that is all we need for a 2 or 3 day trip.
Also since check the ground attach points on the frame, they did not remove the paint and
there was a bad voltage drop between the battery and the main power distribution box.

Here are my rpod mods since we became the new used owners of a 09 151

Straightened out the wiring in the hot water heater/ main power distribution box
put insulating foam around the water lines to quiet down the water pump and rotated
the filter so it would not rub the floor.
Sealed off the air leaks
used spray foam around all the cut outs of doors, water lines and propane lines to add a better
insulated trailer
removed the dvd,tv radio combo and antenna
removed the microwave, since we dry camp this was a 50 pound boat anchor for us
added storage where the microwave used to be
removed a 110 out let and installed a 12 volt outlet
scraped the paint between the main ground points( where the battery negative wire is connected
to the frame and where the ground wire from the frame that runs to the main power fuse block.
insulated and installed car heating pads(ebay) and wired in to main fuse panel.
added a 400 watt inverter to run stuff
added a 2 outlet 12 volt/usb  to charge the phones, etc
next is to relegate the 22 pound table to the trash and make a light weight old school post style table

May I ask what kind of screws do you use to attach that wire shelf in your bathroom?
