Dunbier or Quintrex trailer for 4.2m inflatable boat

[hornet]

So, apart from weight, how does an aluminium frame compare to a steel drone in actual usage, stability, maintenance, etc?

I am thinking of placing it vertically when not in use. Considered a folding trailer originally. But it seems that it is not very safe over 80kph on road. quite hesitating considering my space limitation. But safety comes first, with no towing experience.

For a berth at local marina, does it work for inflatable?

Didn't you get the inflatable boat because you couldn't store tour boat at your place of residence?
If that's the case, where will you store the trailer?

A bit on the pricier side. But did you consider a berth at the local marina ?
No need to worry about storage or size etc .
Cheers
