Best engine ? For Mh

[R M]

I no opinions vary !
What's the best mh engine or the most bomb proof ?
3-0 litre ?
2-8 litre
2-3 litre
Etc ?

30 mph in fifth with all that weight is impressive - but is it a good thing?
It does rather suggest that at 70 you’d be running in too low a gear.
I now have a 9-speed auto box and find that at a steady 55 on the motorway, it’s in 7th - the next two gears coming in only at higher speeds. I don’t really mind how many changes the box has to make (I can hardly detect them, anyway), but I do appreciate the much improved mpg: 2.1 litre (Merc)) auto in 4.4-tonne van gives me 29-ish mpg. The previous 2.7 litre (Merc) manual in 3.5 tonne van gave 24.

it's a 6 speed manual box, and I'm usually up into 6th around 40mph at 1500-ish rpm, quite capable of cruising along at 70 should I so wish. Give me 29-30 mpg solo on a run, down to 26 towing car on trailer. 3.0 ltr Fiat, 4090kg Hymer A-class. I just like the bigger capacity lazy running diesels.
The first line of your reply does rather demonstrate my point thought, larger engine with a wide power band, quite happy to pull along at low revs as opposed to a smaller engine needing more gears to achive a decent amount of power from the narrow power band and maximum torque not being available until much higher in the rev range.

Crafter/TGE is 2.0L and can be 177PS , and in my Knaus has a twin turbo setup and is coupled to an 8-speed automatic.

There is an old saying, but a very apt one:

There ain’t no replacement for displacement…

I'm not a fan of the new Fiat engines apart from the 180 with the auto box, any of them with a manual box couldn't pull the skin off a rice pudding - the torque is poor across the range.

Torque, it's all about it's ability to pull.

VAG now use Ford engines - Ford now use VAG's gearbox. VAG right up to their 2.0 178ps with 420 Nm of torque.

FWD Mercs use a Renault derivative.

For me I'd opt for the Fiat 180 auto (450Nm) or the Ford 130 (385Nm), 165 (400Nm) or the 178 (420Nm)

Do you consider MPG? I wouldn't like the idea of the cost of driving to Spain or Croatia with one of those engines...

Doesn't really matter compared to what you pay for a Motorhome, no point in worring about mpg.

is it eight or nine? Give me a a bigger cc lazy slow running engine with it's wide power band for way fewer gear changes and torque from 800rpm

Not a problem when you have a 9 speed auto box, quite happy with the way my 2.2 performs.

I understand 8 or 9 gears for an auto is not a problem, but they need all those gears because the power band is narrowed as the BHP goes up. You'd start to stuggle with a 6 speed manual and a high HP small capacity engine as the rev range where enough torque is produced gets smaller and smaller the more that horsepower is increased.
