Motorhome vs. travel trailer for our situation

Everyone’s situation is different so I thought I’d ask your opinions on a motorhome vs. travel trailer for our family. Currently we don’t have a vehicle that can tow. We won’t be able to get one for at least a year (thanks used car market!) but we’d like to get some kind of trailer asap. My in laws have a trailer that’s stored near central California coast and they get it pulled out to rv sites nearby. The storage place has a waitlist so buying one and storing it won’t be an option. We do have a large side yard perfect for a trailer but no way to tow it. That brings me to the other option of buying a small motor home. We’re a family of 3 and my son is 5. We would probably keep our travels pretty close to home so probably just the California coast and the Sierra Nevada mountains. I think I’ve covered our situation so what does everyone think? Travel trailer or motorhome?
