it's a hard question to answer @Pasties my 2012 Outback was standard with 15's but I ordered it with 16's the stud pattern is the same as Landcruiser/Nissan/Ranger/Rodeo etc but its the off set that is a problem

Definitely a problem. I don't know about the others but the Ranger/BT50 is +55 offset as against our vans 16" rims being zero offset. Jayco may be using the same zero offset on other rims. The Jayco rims should have on them somewhere what the diameter, width and offset is. It could be marked as ET0 (that's a zero not a letter O) and you can measure what the PCD (Pitch Circle Diameter) is approximately (probably 139.7mm). A lot of the online wheel manufacturer's web sites don't necessarily give you enough detail to select the appropriate rim though because you also need to take in to account the load rating as well. It would probably be best to take a wheel to a tyre retailer and see what they say about matching it up.

I'd love to match the car and van wheels but it would take a compromise rim offset and a different axle length on the van to achieve it. That's not on the current van mod list, yet

I think the 15" s is -9 and the 16"s were zero. I have it somewhere but would need to find it. Iirc you go with anything up to +10. I bought a sunrayasia but they are considerably heavier to carry than the Jayco rim. Consider just carrying the carcass.
