Hi crew am new to this site and have been assigned the project of purchasing a HET for use as a rescue vechile back in Australia ... The pics on the A1 are defiantly impressive ..... . Have any of you guys seen the 6x6 global version ? .. Sounds like you do a few miles in the 1070 dieselfreak shame you didn't have a video of your airborne fun ... Would deftly be a YouTube sensation ... Or a hit on SS at least ... Are all the 1070 s (before the A1) the same or did they change as there build dates progressed ? When did the A1 first come into production ?
The 1070s are mostly the same, the largest differences seem to be related to whether or not they went through a rebuild -
- DDEC III/IV insead of the older DDEC II engine ECMs
- Separate speedometer and tachometer instead of the earlier tachograph
- LED taillights and marker lights
- Blackout marker lights removed
- Battery Disconnect Switch (Particularly Oshkosh rebuilds)
Some of the HETs were sold with air conditioning as well, but not too many. They typically had the added toolbox above the spare tire also. I think the rebuilds were done at Oshkosh and by Red River Army Depot. (RRAD) I believe the Oshkosh rebuilds to be superior.
It seems like the earlier production 1070s are the ones that were rebuilt, whereas the later production trucks have not undergone a rebuild. For the most part, this means the 90s trucks have DDEC III/IV ECMs and the 2000s trucks have DDEC IIs. I think they build 1070s from 92 until 03, but not every year in between.
I think the A1 started production in 2013.
