My slide in camper has about 4.5 inches between the sliding window on the truck and the same on the camper. I'm lookling for an inflatable boot to match up to the two. The only one I can find locally requires no more than 3 inches gap. I could move the camper further forward about 1.75 inchews, though I don't want to.

Several years ago I was able to buy a boot that was much more substantial than the ones now available. At that time, they would handle gaps of 5 or more inches, were made of heavier stuff and had a durable fabric covering much like good quality air mattresses.

Does anyone have a link where I might find something loike that? Has anyone had luck just using a alrge tire inner tube?

Thanks for your help...
