Mate if you get your tyre pressures right you shouldnt have a drama towing a camper trailer...
Every year we go to fraser island with a 2.2tonne Haynes hunter in tow... we drag it up to orchid beach so through all the soft and tricky places... Dont be scared to play around with pressures... When running along the hard sand we usually have the car around 24 psi, and boat trailer around 20 psi, as soon as we approach the first soft and boggy section the boat goes straight down to 12-14 psi and the car down to around 16-18 psi....
If you are in a manual, the trick is selecting the right gear before you hit the soft stuff... the old saying slow and steady wins the race... the amount of people i see charge into indian head on fraser in 2nd gear high range by the time they are 2/3's through the motor has run out of puff and its all over.... I have found 2nd low and 1st high to be the two magic gears... i like to hold engine rpm around 3000rpm, so if i need to give it a few more berries through a heavier patch i have some revs up my sleeve. If the motor starts to die im usually going quick enough that i have time to put my foot down and catch the motor before it comes off boost.... If you start to slow/bog down, dont take your foot off the loud pedal and dont punch it to the floor either... just hold it at 3000rpm and give the steering wheel a bit of a shake from side to side. Most times the front tyres grabbing the edge of the tracks will help to worm it through... If you start to really slow/bog down but still making crawling pace, back off the throttle to around 2000rpm, while you still have forward movement there is still a chance it will grab some harder sand eventually.... The second you stop going forward or start diff hopping stop!! Grab reverse and try to back out.... If you start bogging down in reverse, stop!... disconnect the trailer from the car, dig the car out, drop another 2psi from your tyres. If you can, re-connect the trailer from another angle.... If thats not possible and you are really stuck, pull out a coldy sit back and wait for someone to come by and give you a snatch... Doesnt matter if you get bogged, there is always a way out...
But just remember it happens to the best of us... mum and dad have been going to fraser since 1974, towing trailers, caravans, camper trailers and boats and always been pretty fortunate... until this year... First trip towing it with the new 200.... even with its 4.5L twin turbo V8 diesel throwing ponies left right and center.... Dad had to pull out a coldy and wait for me...
But we got it out...
