Twin axle for anything that heavy. I have seen too many wheels flying off single axle trailers and had three incidents where my trailer nearly came a cropper.
Once on my previous single axle the wheel cracked right across (heard a clicking noise going round corners and found it was the whole inner wheel just about to separate from the outer with no warning.
Had two punctures on my current twin axle over the years and no hassle to sort, if you do it right you don't even need a jack to change!
I also wind up the jockey and can manouevre it just as easy as a single axle

Not all twin axles can be towed with a missing wheel. I have had a wheel fall off and the disc was scraping on the road.

Keep the maintenance up and you should be fine with the type of distances you do. The quality of the trailer is more important in my opinion. We have had an influx of Chinese made trailers in Australia. They have way to much flex and corrode very quickly. I have seen leaf springs rust to breaking point within a year.

Ok going to throw my bit in, i over spec trailers, under my rib I have a 4 ton capacity trailer and as kubcat said, some 4 wheel trailers won't run with a wheel missing, if you can afford to over spec do it, I don't mean just money also trailer weight.
One point I'd like to bring up, if you have a boat and 4 wheel trailer that is close to its maximum capacity be careful how you bump up kerbs, you can lift one set of wheels off the ground and put all the weight on one axle, they can collapse

Regarding bending of a trailer being used at or close to its maximum capacity we have one of these under the 6.5 Scorpion. :ROLLER COASTER 10 | Roller Coaster | Marine | Leisure | Trailer Range
No problem with bending.
Bearings all good after 8 years.
Replaced wheels and tyres at 5 years old as a precaution against ageing. Never had a puncture.
I will admit that the brakes are now rusted out but that's not a single vs twin axle thing.
Tows well - I've never thought " thats unstable, I wish I'd bought a twin axle"
Tow cars have been old Range Rover, old discovery, Volvo XC70 ( max towing weight 1800kg) and currently a Volvo XC90.

Most of our towing is a mile to the slip and back and then a 20 mile round trip for servicing once or twice a year.

When we bought the boat we were supplied with much lighter trailer - similar in appearance to a roller coaster 3 with the single side rails. We towed down to Falmouth and back (from Hamble) with no problems although the trailer frame did have a noticeable bend in it. Changed soon after! I wouldn't advise overloading a trailer but we weren't instantly killed to death the moment we hit 60mph.

In my opinion a correctly specified single axle will be sufficient for your NEEDS.
However, I don't disagree that a twin axle will give some redundancy if you have a puncture. It's up to you to decide what you WANT.
It's fun buying new stuff isn't it :-)

The construction of the one that bent was very similar to this one:ROLLER COASTER 3 | Roller Coaster | Marine | Leisure | Trailer Range

As I said above it got us to Falmouth and back - although maybe we were lucky in that respect!

I also like buying new stuff, but on occasion refurbishing old stuff is equally is fun too, we decided against replacing the SBS 1800 EL as basically the frame etc was ok, just needed galvanising to bring it back to new, we've also replaced all of the U bolts etc and will be fitting a new axle as well, overall the cost will be less than half the cost of a new trailer, and has been reasonably enjoyable so far

thanks for the replies gents.

I'll update the thread once i know the actual weight of the rig, should hopefully find out mon/tues when it is put on the forklift. that ultimately will make the decision for me i would think one way or another.

cheers

Things just get bigger and heavier as you get older, I've put another 3 m in this trailer to take my sunseeker

Looks nice.

Ours will be getting a new axle in a couple of weeks.
