I messed up my floor

I have a 1997 Winnebago Chieftain. We decided to replace the carpet and old linoleum with new self stick tiles. The removal went well and putting the new tiles worked great and we are very happy with the results. Now... This is where I messed up. When cutting out the old carpet and linoleum from under the slide. I put the slide (kitchen and sofa) all the way out and cut the old flooring. So, as you can assume, now when I run the slide the stuff under the slide is catching, bunching up, etc. With the slide all the way out I can see a couple of parts sticking out the exterior between the bottom of the floor of the slide and the top of the basement storage (I can't reach to cut it off). But, I know that there is more still under the slide flooring. Please, please tell me that this is something that can be fixed without costing me millions.

Sorry for the long post and thank you in advance for any help you can give.
