Chattels and joint ownership

Is there a presumption with chattels that the chattels are held as joint tenants rather than tenants in common unless there is evidence in rebuttal? If not how do you establish whether chattels are held as joint tenants or tenants in common. The case in point is a mobile home and we need to establish whether it passes by survivorship or under the will.

The property is assumed to be held as joint tenants unless there is some evidence/indication that the parties involved intend to each hold separate shares in the property in which case there is a tenancy in common.

The general presumption being that equity follows the law; joint tenants in law will be joint tenants in equity.

I am not aware the “rules” for chattels are any different from those real property.
