You know that gap that is on either side at the
FRONT of the bed ?? rubber seals liner
does sink into it when locked down but at lower pressure than the solid flat area...
No leaks..BUT...I can also add a "cut to size length/width" rubber 1 side tape to seal that gap. ( no need..but I can help prevents )
Every brand have their flaws...It's how you approach it making
IT works for your needs. >

:grin:
:wink:
1st pic. ( front panel is
unlocked & liner is uncompressed..center bar is only hand tighten at this point...adjusting corners & sides..
not easy as you get a bit eyesight illusion due to diamond patterns.( see note/post about my right front corner :nerd
***keep that in mind as the diamond patterns and rubber liners sticking out at certain points
WILL make you misjudge the
true line ups...etc.***
...cardboard is there to prevent scratches )
2nd pic. ( just to give an idea about the diameter of the seals rubber/liner/tube ) :grin:
3rd pic. ( ignore the spare :grin:..meant to show the 2 gaps on each side of the front of bed..(created by the plastic trims...sorta like square grooves/channels )...also in 1st pic.
4th & 5th pics ( showing how the generous size liner/tubing compressed after locked..as mentioned above in underlined ( use of filling DIY should further improves...but not necessary.)
