Storage container storage
Discussion
A lot of containers don't have sealed floors and are sat on, or over, damp ground.
At night, the ground is warmer than the container, so water vapour leaves the ground and condenses in the container.
best thing is to cut off the water at source with a damp proof floor and/or lots of ventilation under the container.

I've got Permabags which I've used for years on cars and bike and they should work well in your situation. You do need a bit of room around the vehicle to zip up the bag.
I've also got a "Carbag" which is an American version of the above. Not as robust but quite a bit cheaper. Permabags are pretty expensive now. I got mine almost 30 years ago.
Do you have a link for the liner bags you mentioned.

Easier said than done to just get alternative storage as it has to be secure and hold my car and bike. I’m more interested in what people have done to combat the issue, I’ve looked at a cartoon but need power, I’ve looked at PermaBag which is a strong solution but I’ve also seen a company who sell linear bags for storage containers (for grain) which I potentially could adapt, place industrial moisture absorbing material, vacuum (slightly) and then seal.
I think this would work pretty well but before I go down this route I wanted to see if anyone has tried something different with success.

Bit cheaper than the Permabag but more difficult to use in a confined space as you need to roll the bike into the bag then seal it at the back, whereas you can roll the bike onto the Permabag base and zip it in.

I work in the manufacture and conversion of containers industry and we use a product called Grafo-therm (https://grafoproducts.co.uk/). We apply using a spray system, but there may be other forms of application.
Every standard is one trip I have worked with has vents cut into the corrugation towards the top and bottom, to allow air flow. Although I will agree they still sweat regardless. If you are allowed, you can cut into the container and put in your own larger vents and perhaps a dMEV fan.
If you are happy to lose 94-100mm in width, you can frame, insulate and overboard with ply, which can be done in one day. Essentially building a box within a box so no fixing required to the container exterior walls or ceiling.

I bought a new (one trip) 20' container in 2020 with high level vents and I've never noticed any condensation.
I keen surplus house stuff, a quad and a motorbike in there with no deterioration.
That's a bit different to most though. I've got one that's perhaps more typical - wooden floor and no ventilation and I don't keep anything other than scrap in it. I don't doubt they can work and perhaps should have said that.I keen surplus house stuff, a quad and a motorbike in there with no deterioration.

The best are the new Corten Steel ones with resin bonded bamboo floors and vents all round.
