Just bought a used Damon Intruder Class A...'95 model. Has an Emerald 4000 gen. Had a 'C' for years with no generator. First: The generator is mounted at a downward angle towards the front. Is this normal, or is there a broken mount? Not knowing the previous owner's habits, I decided to change the oil and filter. Drained the oil into a 'used oil' container I have. Filled with the 3.5 qts printed on side of gen. Checked the stick, Looks like it's way overfilled! The bottom of the sump looks almost level with the ground. Appears I may have to drive it up a hill to change oil! Any advice? Thanks, Bill
