Been lurking here for a bit and did some searching but just can't find an answer. I have a 2008 Sierra 316BHT and it has heated tanks with two black and grey and a single fresh tank. My question is which tanks are heated? Are they all heated? Just the grey and black? Thanks
Thanks Dave, pretty sure I have two black and two grey. I have four dump valves two in the front and two towards the rear so thats why I think that, also the trailer has two bathrooms one front and one rear.
