For comfort, I’ve always liked MAN’s and ERF’s, I just get comfy in them. But the MAN auto box is a pain in the harris.
Scania are nice for being quiet and actual cab comfort, but that seat - well, I got comfy in the 2010 onwards ones, no idea if they’d changed or I just found out the correct adjustment. The 3 over 3 gearbox can be great or can be a pain in the harris, false neutrals happen more often in that truck than anything else I’ve ever driven. Also, why do Scania’s suffer more than most with cruise control knocking itself off for no reason? Chilling on a motorway, and all of a sudden, that truck you passed ages ago is passing you, oh look, you’re down to 48mph, better wake up and press the throttle, but better let him finish his pass first, then pass him again 
DAF, great truck for the 1st 100k, but it’s not very nice being stood next to it, whilst it’s in for a repair AGAIN, and if a fat git uses it, the seat collapses far too easy to 1 side. The XF has the best bunk I’ve ever slept on. The CF seems to have a draft from behind the bunk, never found out where it came from or how to get rid of it.
I’ve always liked Volvo’s, but I’m driving a FH 520 80th anniversary special edition now with all the bells and whistles, the heated part of the seat doesn’t work but the cooling part does, not sure if it’s because of the heated part not working, but I’m getting terrible back ache, like leaning on a cold wall back ache, will be trying to fix the heater part on monday. Engine and gearbox are ok, not as special as I thought it’d be. The ACC had to be disabled by me on my 1st night after it kept bleeping at me there was a car too close in front, and if I had the retarder on (A) it’d keep braking too, so had to turn it off (A) which meant I ran over 60mph a few times over Shap.
The Merc Actros was probably the truck that fit me best overall, but it kept spilling my brew, and I will never forgive it for that, crappy cup holder and on some a crappy drivers door blind.
On tippers, I drove a 54 plate MAN and an 07 Hino, the MAN was great, good gearbox and clutch and engine, but it bounced like mad - all leaf spring 8w - and had the steering lock of the QE2, the HINO was good but it was brand new, you just knew it was going to need LOTS of repairs soon, lots of squeeks and rattles and loose fittings.
I like the (newer) Renault Premium, but I’ve no idea why they don’t make the cab the same width as the steps / trailer / box. I hate hanging out of my door trying to line pins up at Felix. The old Premiums were ■■■■■■ the knocker gearbox was crap, the seat was crap, it rattled like hell and half of it didn’t work.
Didn’t rate the only Magnum I ever drove, but it was an old X reg, and was just not a nice place to be, horrible interior, feels like sat too close to windscreen, dash looked like it was out of an old Renault 25 and it used to scrape going into and out of most of the yards I delivered to, so it had to go before the fuel tank fell off - it was the strap that was scraping. Would love to try a newer one though.
I hate Merc Haxor’s with a passion, except an 11 plate 1 I drove with the Actros automatic box, I’m assuming it also had the Actros seat as it was just nice, normally I can’t get comfy in them. But still a truck I’ll do my best to avoid forever.
We just got the new Merc Actros at work, but I was in a rush so didn’t get a good look round, I’ll see if it’s in the yard on days and try and nick it.
