My Troll is just 10 years old. Its done kept outside and done around 7,000 miles. I am just planing my usual trip down to Spain and thinking perhaps I should be checking out a few items i.e.wheel bearing might need a grease up....any other advice that could/should be checked out (advice as to how I check out the wheel bearings would be helpful).

I usually get my Triton serviced every year, we have a section on service engineers here

Caravan servicing and repairs, including mobile technicians.
