thanks for the replies. It's looking like the tandem is winning here! I had thought about the weight distribution and it'd likely be a lot safer and less stressful to tow with a tandem. I'm looking at moving a B6000 by the way, which is comfortably 7x4 let's say, but I think could squeeeze on a 6x3! Considering I may well be needing a FEL down the track, I really should think about giving some leeway there. In an ideal world i'd like something I could also move building materials, furniture and such like with too as it'd probably be my only trailer.
small&mighty99, that dovetail idea is brilliant, how easy must that be to load! I'm thinking about getting a secondhand tandem trailer then having an engineering company put one on for me. Great pictures too, thanks for all the advice.
So, maybe i'm now in the running for something of between 5x8 and 5x12, tandem, or thereabouts.
thanks. Any more thoughts greatly appreciated.
