Yes, they sell "as is". ALL used RV's are basically sold that way. But, the systems should be functional AT DELIVERY. You have a couple of problems
1. The A/S has a Macerator system. I would be worried that IF there is any water in either tank, that means the dealer did NOT do a correct winterization. You CANNOT winterize the A/S macerator system unless you completely DUMP both tanks and then run RV antifreeze thru either tank to run thru the Macerator. There is NO OTHER way to run RV antifreeze thru a A/S macerator. This means the odds are the macerator pump has frozen AND the 15 foot 1 inch drain hose on the reel is frozen also. I service A/S motorhomes and trailers, so what I post is correct.
2. Yes, they use the inductive type probes, but you can have defective pads causing a false readout. Easy to replace if needed. Doug
