Sploom:
If you drive 200 miles, and realise you forgot to level it, does it do the trailer any harm?
Yep.
It’s gonna send a message via microwave satellite to a telescreen monitored by a pointy shoed holder of a ner do well degree in social sciences or some such who is going to hurl you into financial purgatory and your children into slavery.
Or it may have worn a little bit off the tyres.
Whatever, no one died and now you are that bit more of a conscious driver as a result.
Carry on.
