I have my TT on a permanent site. Currently it is leveled by blocks underneath the tires. Should I block it off around the axles and frame and remove the tires? The site isn't completely level and the back end of the trailer hangs off an incline.

thanks for the quick response! Sure do appreciate all you guys and your opinions. It helps us newbies!

When I winterized last year, I didn't have the hot water heater completly bypassed. Antifreeze got to into the tank. How should I rinse it out?
