Enclosed trailer help

Hey guys, I’m currently storing my 3 Atv’s at a storage facility as there is not enough room In my garage to keep them here. Therefore I’m thinking of getting an enclosed trailer to park at home. Covered storage and cheaper than Building a garage. I would like an aluminum v-nose trailer, an awning on the side to hang out and BBQ at the trail heads. A couple questions.
How long of a trailer to fit 3 ATVS in line?
The future may have 2 SXS and no Atv’s length would need to accommodate that.
I was advised to order a trailer 7′ high door opening for SXS roll cage?
Do you tie down ATV In an enclosed trailer?

Thanks for any help and reccomendations.
