Review on 📦 Mor/Ryde SP54-099H Under Step Storage Box Black, 28.5 Inch: Efficient Solutions for Onboard Organization by David Cronin

It's great to have more disk space. The box is well assembled but not sealed. To fit a Jayco fifth wheel proceed as follows: 1 Remove the original rungs, 2 Drill out the rivets and remove the ladder mechanism, 3 Cut off the bottom half of the remaining frame, 4 Reattach the top of the ladder frame reattach, 5 Hang onto the two box brackets and drill out the trailer bracket with rail brackets for the second bottom set of holes 6 Rehang the brackets using the new holes (now about 1" under 7 Mount the box and load overall not a bad job but does take some time, patience and power tools. I love having extra storage
