My 2015 came with a 50-amp slow-blow fuse that tripped frequently during hydraulic slide actuation. Got worse over time (since thermal properties worsen after repeated tripping). Had it replaced under warranty, but problem started again soon after. I called Lippert, the makers of the hydraulic slide/leveler and pump system. Tech guy told me these identical systems installed on more expensive motorhomes are installed with 100-amp slow-blow fuses. He said he can't technically recommend that because the RV manufacturer is the one who installs the fuse....and the wiring. I measured as high as 80 amps during slide afctuation, and determined my wiring sufficient to accept up to 100 amps. I purchased and installed a 100 amp fuse. No issues since.
