Cumbria biomass work questions

Shouldabeenajoiner:
Interested in working for either Aw Jenkinsons. Dent logistics or Stobart group. Which on is best. Im leaning towards Dent smaller company, nice variety of work/ places to see, have decent trucks and most are back by tea on a friday etc only downside is no truckstops paid laybys only.
Someone sell me the job good and bad.

Free diesel?
