I have the Isi 4x4x4 off the back expensive but worth it 24k incl 3k corrrgations/dirt. It’s awesome no bikes touching easy to swing up and down for expands bed ends, 2 person to lower though, unless taking bikes off, isi 4x4x4.

I had a guy in kirrawee, Sydney, he take the Jayco bar off and welded through the bar a 50×50 square tube it goes under van and is screwed to chassis cross members underneath with bracket about a meter…. … a 40mm tube welded through bar and from underground shot straight forward. Welded another support from left to right welded to chassis on each side, cost 220 together, solid as now
