Need specs on my Class A

The chances of finding what you're looking for an a 2 year-old RV are small. On a '98 they're almost invisible thorough a microscope. We have all the documentation the original buyers of our rig got, and although many of the vendor documents are useful, the documentation from FR is pathetic.

BTW, since the brand name is "Coachmen" (plural) I'm not sure the above links will fly.

Try here: Coachman RV
or here: Coachman Owners

If you have access to the tanks where you can measure them and assuming they are square or rectangular, you could do the math yourself and calculate the capacity. Length in inches times width in inches times height in inches divided by 231 will give you the gallon capacity of a box shaped tank.

I would tell you to find the owners manual online and the info should be there. But you say you've already done that and it isn't there so I'd be stumped. The owners manual should be the source for that kind of information.

The chassis maker may have the fuel tank size, but the other holding tanks are installed by Coachmen so the owners manual should have had that.
