I had one for a couple of years and found it fine for general use. Never had a problem
I found that on the sand you had to get the revs up enough for the turbo to kick in for it to work well, which could if not careful lead to the wheels spinning and thus bogging.
Over all though I was very happy and only upgraded when I bought a boat. It was 24', fibreglass and over 3 tonne on the trailer. The 2.8 was just not up to the job.
Cheers
