Based on my research on the Karavan Trailer website most of their snowmobile trailers such as their Ultra-101-12-WB use hubs with a 5-on-4-1/2-inch bolt pattern. The supplied wheels are 14-inch and are fitted with an ST205/75D14-inch tire, which is a load range D tire. The wheel/tire you referenced, part # AM3H325, uses this same 5-on-4-1/2-inch bolt pattern.

If you need to replace a hub you will need to confirm both the wheel bolt pattern (see the linked article for help) and also the bearing set used inside the hubs. A new hub must use the same bearing set or it will not properly fit on your axle's spindles.

The linked photo shows the typical location and appearance of bearing part numbers. Once you have these you can easily search out site using the included link to find 5-on-4-1/2-inch hubs that use the same bearings.

If your trailer uses idler hubs (no brakes) then you can use the link provided to select your bearing set to then see suitable hubs such as # 84545BX which uses inner bearing # L68149 and outer bearing # L44649.

If your trailer has drum brakes then use the other link to see hub/drums in the 5-on-4-1/2 bolt pattern, such as # 84546UC3 which also uses the same bearings.
