Thanks for the update.
I've been wondering how the drive was going the last couple days. 20 mpg on those few tanks is very impressive for the big benz with the big block.
With my frequent business travel, I stay mainly at Marriott / Courtyard's and Sheraton / Four Point Sheraton's, and you'd be surprised at the number of locations that don't have high speed internet connections.
Sooooo, you've decided to stay long-term at a Hilton. How long-term? That seems kinda pricey.
Are you still thinking of buying an inexpensive house?
Regarding the valve stem seals, you can't be too far from a fellow member with a garage, can you?
MedMech / W126 / Gilly live in the area don't they?
