Rosie and her brother michael decided recently to purchase an rv together. they both want to use the rv to take their families camping. the price for the rv was $10,000. since michael expects to use the rv 60% of the time and rosie 40% of the time, michael contributed $6,000 and rosie contributed $4,000. their ownership percentage equals their contribution percentage. which type of property titling must the rv be to reflect their ownership interest?
