[ausev] This weekend?

[Kevin Koym]

I do not know the details about the truck mentioned below- I have just 
been a lurker for  short while on this list- but wanted to share an idea 
based on my previous experience working on cars (at some point I will 
have an EV)...

On removing the battery pack- any chance that you can have the truck 
towed to a "work bay" that has the truck on solid ground, with a work 
area underneath?  (you have probably seen this before at a place like 
Jiffy Lube).  Just an idea- the truck is supported, and another device 
can be used to lower the battery pack onto (inside of the bay).

Glad to see y'all organizing Austin for EVs.  Thanks.
Kevin
