You are correct about the rollover protection and special lid required but, unless the rules have changed recently, the max of 1000ltr and parking 100' away from anything else aren't right.
Under ADR you need a minimum of a 9kg powder or 9ltr foam extinguisher and a spill kit.
Choosing a parking place, from memory -
- In a secure, manned vehicle park
- In a secure vehicle park
- In a place where traffic and the public are least busy
- As out of the way as you can get it
Also the towing vehicle doesn't just have to be 1000kg heavier than the trailer - it needs to be rated by the manufacturer to tow the weight of the trailer. The best UK vehicles are LandRover products as they have (or had) the highest permitted trailer weights - 3500kgs.
I towed a 3300kg/2000ltr Jet A1 bowser legally for 15 years, until mid 2006 - full ADR. I must have been OK because I was given the third degree twice at DoT roadside checkpoints without problems.
I will repeat though - unless the rules have changed in the last 2 years.
