You will here a lot about a driver shortage in this industry, but it is a total lie. There is shortage of drivers willing to work for peanuts and poor conditions. Those companies constantly advertising are doing so for a reason. It usually means they are rubbish, either rubbish conditions or rubbish wages, more commonly both. The less said about Stobarts in that regard the better. That said, as a foot in door to gain experience, don't discount them, they will usually take anybody competent enough to make it to the gatehouse without wrecking the truck.
Most of the better jobs rarely, or more likely, never advertise because they know how to retain drivers, and the only way in is "dead mans shoes".
Your earning ability will depend heavily on where you are in the country and what work you are willing to do. I live in the midlands, near the M40, M1, M6 and A14. Everyone and their dog has a warehouse and distribution operation round here, hence wages tend to be a little higher than areas with fewer jobs. Class 2 usually £12p/h or higher, Class 1 £15 or higher not uncommon.
My job is multidrop, but dropping and swapping cages, we don't touch the stock at all. 4 on 4 off shift pattern with 6 weeks holiday, we are salaried, but works out just over £15p/h for 18ton rigids. We average 4 or 5 drops per day, but its a max of 27 cages regardless. I find it some of the easiest work I've ever done, but some drivers wouldn't even look at it because of poverty spec trucks/central London/multidrop/pushing cages/health & safety rules...pick your excuse.
You can only take so much advice as everyone has a different take on what is good and what is bad. I've only slept in a truck 4 times in 20 years, so for some I'm not even considered a "proper" driver, but I don't wet my bed if I have to drive into London, so it really is about finding your niche.
Don't take one job and be put off the whole industry, everything is different and there is something for everyone. Tippers, trunking, general haulage, recovery work, exhibition work, store deliveries, home deliveries, car transporters, bin wagons, don't rule anything out.
Stobarts though......you still get the tragic Eddie spotters outside the A5 truckstop at Crick. Maybe they are trying to spot the only wagon not to a hit a bridge yet
As for the YouTubers, no different to any other dashcam heroes, driving in such a way to manufacture conflict or situations just for drama. Ignore them. I put them in the same box as the bores who were on the balcony in 1980, or missed the Herald of Free Enterprise by 5 minutes.
