When I moved up from vic I had an 8x5 I was towing with a double bed standing up vertically, a fridge, all the woman's clothes (bloody loads of em!) a small toolbox and a big one https://www.aulro.com/afvb/images/im...013/04/872.jpg
And I could do a steady 90 with ease 110 if the go pedal was half way down apart from on hills. The blue box weighs a LOT it's full dont know the specific weight but I'm sure I overloaded the trailer. Couldn't do more than 60 on the hills out of Sydney but on the flat she was ok. Was using my 3.5 flapper and the rear springs were compressed rather low from the weight of it.
