Default Trailer access calculation?

Thanks Martin. I think that after maybe another week or two of
lockdown, I'm going to be bored enough to make something around
my aluminium ladders using a couple of spare wheelbarrow wheels
and some scraps of timber. If I can get the ground clearance right,
as well as the total length, width, and wheel position, that should do
it. And it'll keep the neighbours amused.

I want to bring my trailer home to do some maintenance while

we're all
grounded, but I'm not sure if I can access my house from the

road. I
have a 90deg bend to get around and then the second issue is a

steep slope, which may ground the back of the trailer.

So my question is, if I measure things up, how can I calculate

access is theoretically possible? Is there any advice on the

internet -
I can't find anything?

I don't want to just try the trailer for size because I fear getting


You could always model it:

1) use a 25m tape measure +_ compass to draw an accurate map

of the track
on a decent sized sheep of paper, say A3 and use a sensible scale,

1:25 or 1:50 Draw in the track to its correct width and don't forget
obstacles, (hedges, poles, gateways, buildings etc.

Seeing that there's a steep slope involved, use some scrap foam

to make a scale 3D surface and glue the map to it I'd use a hiking

GPS or
Google Earth to measure the height difference unless you already


OR (in order of decreasing accuracy)

Walk the track centre line with a GPS


Take measurements off Google Earth

2) measure length + width of trailer + towbar and towing vehicle.

cardboard cutouts of the plan view of trailer and car. Add a scale

to the trailer (lollypop stick would be fine) and add something to

trailer where the wheels should be. Rubber toy wheels would be

best, but
small blocks of wood or foam should also work. Connect car and

with a drawing pin or similar, placed where the tow ball is in the


3) now you can move car+trailer models along the track and see

how close
the trailer comes to hitting anything.

At least, thats how I'd do it and, even if it takes time to do

its something else to do while in COVID lockdown. Making the

can reasonably be described as 'your daily walk'.
