I'm still only halfway through my conversion. I have the three GU IV rims, and the 33" KM2s for them, but the rims only just fit with the 31" Grand Treks on them.
I need to:
- cut the trailer guards off and re-fit them higher up, or
- lift the trailer by cutting the spring hangers off, welding a metre of Duragal to each side of the chassis and reweld the spring hangers (that's what Jimboomba does for big wheels)
- flip the hitch to accommodate the extra height - I have a DO35 so no door clearance issues there
Then buy a new axle that is maybe 75-100mm wider, to get the same track as the Patrol and allow the 33" tyres some room on the inside for suspension flex. I already have electric brakes and Patrol/LC stud pattern so no probs there.
Then get some work done so the tent can handle the 5" lift. The zip-out floor helps, I could just get a strip made up with zips either side to go between the floor and the tent walls.
But all in all, a fair bit of work and expense, and it's fine on the GU IV rims and road tyres for what I have been using it for, hence the procrastination.
