i see you pull a stacker trailer also. If you dont mind I have a few questions. Do you have the 15k hitch? also how is it getting around being aprox 80ft long?
If you have trouble climbing the ladder, why not get someone else to wash & wax the roof for you? Pay a young man to do it for you; save your back! Ditto for troubleshooting a blocked drain line. Ask Tiffin for the exact location of the underbelly drains. Inspect the duck-bill fitting at the discharge end to see if it's clogged.Also... you just might be able to "blow-out" the line from underneath with a short blast of compressed air.
