Got my 186 back today after a month in the shop. They adjusted the slide so that it now comes all the way in. Fixed the gasket on the throne which put water in the shower when using the black tank rinse, and replaced the plastic molding on both sides that runs along the top from front to back. Also had the heat strip installed, but at 94+ degrees haven't had a chance to test it. If a 5K BTU air con can cool a 144 square ft room, a 5K BTU heater should be able to warn a less than 100 square ft RV. Will follow up on this when it cools off here in S. Texas. Also bought some super grease to do the wheel bearings. Need to add a battery cut off switch and i'll be ready to hit the road. On the road again, I just can't wait to get back on the road again.
