yep, we have a multi policy for home contents, cars etc with RACV. CT insured under their Caravan policy for agreed value and up to $1k access.
Ours is AAMI. 3 cars, house/contents plus the Jayco. Camper renewal, came in October and I wasn't happy with the value given the recent work to the camper. Plus it was insured as a "Jayco Eagle 4cyl DOHC, 6 Speed Manual"... Apparently a common glitch in AAMI's data base?
Explained all of the mods and accessories fitted. Upped the agreed value by 3K to 17K, upped and annex/awning cover to 2.5K and with the 1K contents cover my premiums went up a total of $8.00... and still under $300.
Never made a claim, so I can't comment on what they're really like.
