I have used track mats and ski guides for yrs and wouldn;t want a trailer without them
replacing floors sucks LOL
there far from perfect however, and do trap water under them and can be slick to walk on
but if you have studded tracks , the stud mat's will add yrs of life to your floors! IMO
IF I was to do again, I would be using the traction ski guides they have now, they are a LOT less slick when wet or snow covered!
if not thru whole trailer at least use these on the doors/ramps!
I still prefer the more solid track mat's however, as there easier to sweep, than the one's with sections missing are IMO!
best time/place to buy these things , for me has been at snow shows, when they have them THERE and offer special pricing on them
IF you have a treated deck now in trailer, I would also recommend you do a new coat of waterproofing before you add them, as again, water and ice get under them and can sit for a while, so added layer of waterproofing isn't a bad idea!
all the more so if you already rode a few sleds with studs on floor and now have little pin holes LOL
use good stainless steel screws too when ever mounting them
GOOD track/ski guides will have slots, so things can move some as wood contracts and expands with temps!
there not really made to be super tight to floor!
