I just replaced the wiper seals on or 250rb. Norco R854056, 1-1/2Ē. Bought on Amazon. About $100 for 25í. Camping world quoted $200 for seals and 6 hours labor at $150 per. Took me about an hour for all 4 seals once I figured it out. Used some seal conditioner to lubricant the slot. Old product pulls out hard. New product slides in. Took two people, one to push and guide. One to pull. On the inside you will probably need to take the wood trim off of the slide. Outside wiper seal went on easier. I looked at the adhesive ones but didnít think the would hold up.
