Bought it in the fall of 2015, had a rustler 5th. Haven't been out yet, here is what I have done so far.
Solar maintaner, 12k equalizer, power jack.
Couple "kid improvements", the bunk ladder works great(not my best work but it was a rush job)
New taps(with shutoffs&braided lines)
Rewired the lights in bedroom,bathroom & bath sink, to a wall switch used the existing switch on the fixture to select 1or 2 lights on with wall switch and put 48/36 LED panel lights in all fixtures
And these levelers from anderson are the cats meow
Thanks for looking, any questions fire away.
