Trailer and camper maintenance

[the evil twin]

snip... Ill be fitting an 82 litre water tank under the back of my camper to help balance it out.
Its atad front heavy for my liking at the moment

Trying to balance the Trailer with water can cause it's own issues.
If you put the tank too far back from the axle you may get trailer sway.
If the tank is empty (IE your on the way home) you are back where you started anyway.
