I think it looks promising and might even find your slide will ride on it nicely if you make sure to sweep it before bringing them in each time so you don't grind sand, little rocks, etc into the new flooring. Don't ask how i know.
We used Allure to replace all of the non-slide flooring in our coach... both carpet and vinyl tile. I've had some problems with my slides putting scratches in the flooring but I think two problems caused this. First was the fact that I used a 1/4" plywood underlayment where the carpet had been in an attempt to get a "flat floor" look with the new flooring instead of having any sort of transitions. This resulted in the area which had been carpeted having a slightly higher floor than it had before. I didn't use any sort of 1/4 round "ramp" or the metal transition strips you mentioned... I should have. The slides (skids not rollers) caught on the flooring when I first retracted them. I ended up trimming both the Allure and the plywood underlayment at an angle to form a sort of ramp for the skid to ride on but I had to tack the Allure down along those edges so the floor is not floating.
The second problem that contributed to the scratches had to do with the carpeting which was OEM and if you don't have carpet you're lucky. Winnebago uses a real world class glue to hold that stuff down and I didn't get it all out on the first two tries. It attracted little rocks that scratched the floor.
I can replace the damaged planks and will probably install at least a metal transition strip... it on my list of things to do.
Good luck...
