air jacks ! don't be so lazy !!!!!
I took the 'fibreglass/resin' sand/bridging mats, about 4ft long.
From UK to Korea used them just twice. But boy oh boy you appreciate them when you need em.
These 'griptrack' look a good (and cheap) idea, easy to store n carry and easy to use. I agree with Marty that perhaps buy 2 or 3 sets.
'Air Jack' - I would class tha as a luxury item !!! simple, solid bottle jack or if you can make use of the maybe a hi-lift jack.
My issue always with jacking was the bloody thing wanting to sink into the mud. Find a handy piece of timber to act as a foot.
