Hi Anton
Ditto with the 2nd & 3rd gear experience........only realized on the last (& highest dune), that the Padj went up, seemingly without hassle, when in 3rd gear.....not 2nd, as I had been using for all dunes prior....
I "HAD" to do all dune climbing without rear diff-lock, as the diff-lock vacuum pipe pulled out, after the suspension lift (and fitting w/shop did not realize the necessity to lengthen + the rear diff breather as well !!)......
BUT......the Padj is such a fantastic vehicle that, with a little changing of driving skill / tactics.......seemed to overcome almost all & any obstacles that Atlantis dunes could throw........and mechanical hiccups

Negativety and Non-enthiusiasm are the only obstacles we shouldn't encounter "
