  SXRguyinMA, the RAM Power Wagon is in the Offroad class. You will need either the Unimog, the Mercedes Tankpool24 or the Volvo Iron Knight - those are the only 3 vehicles in the Truck class.

  As an alternative to the first solution, you can purchase the cheaper Mercedes Benz Unimog U5023 and equip my tune, called 'Ground Force'. Use the same danger sign, Ambleside Edge and you should hit the 3 star target straight away.

  Didn’t mention the 400k price of the tune..

  I managed to get a Unimog through a Wheelspin. I wasn't stoked so much about getting this particular vehicle but more excited because it wasn't a horn or a pair of pants.

  Great tune and solution. Just a note for those like me who had already 3 star'd the sign and couldn't get it to pop: completely exiting out of the game and starting it back up made it pop as soon as I got in my car.

  A much cheaper alternative using the Unimog, I did this for about 85,000 Credits.
  
  I bought a Unimog off the Auction house for 55,000CR buy it now (trust me they do appear quite regularly at that price). If you're not too bothered just buy one for less than 100k, if its been tuned already then its a bonus.
  
  With tuning I only upgraded it to Max class C 600 which only costs around 30k compared to the 400,000k plus using S1. The tune i used was called Cheap Power under the suggested tunes tab.
  
  You can also upgrade it to class B quite cheaply. Just search for class B tunes, there are lots. It's probably a lot easier this way but its definitely possible at class C.
  
  I used the Ambleside Danger zone for this too, you need to get to about 120 MPH which is fairly easy to do if you go back far enough. It'll take a few attempts, just use the rewind tool to get the best angle.
  
  Straight after I sold my Unimog on the auction house making a bit of profit.
  
  Note: This is much more difficult in winter, I recommend either waiting for another season or upgrading the unimog to a higher class (S1) if you don't mind spending A LOT more credits. At the time I was saving for the castle so I couldn't afford it.

  I agree closest I can get is about 175m, can't even get up to 118 mph

  I'll add the tune i used maybe that's the issue, also would winter have an effect on it? I did mine in summer, obviously the roads would be different. Just a thought.

  Ok guys I've just tried it again on winter and couldn't do it, i upgraded to 660 as above did and i got to 117mph, it seems its a bit slower in the snow unfortunately, sorry guys I didn't think about that.
