Budget trailer cameras and storage ideas for trailers without tack lockers

[Ribbonblue]

Hi I was just wondering if anyone has any recommendations for a budget trailer camera? And also, looking for trailer storage ideas. Our trailer doesn’t have a tack locker and just wondering how people transport their things in their trailer?

Can you put them in your car instead?

My boot is always full of crap. So I’m having to dump everything on back seat, so ideally would love to be able to transport it in trailer some how if I can.
