You always need some where to start and on the Newmar Corp web site which is in
this sticky top of forum that has all your Newmar info plus
info from other helpful members you will find
this information.
Highline coach product
line pricing.
Where you hit the compare button where I already selected, King Aire & London Aire, compare the two coach's.
If some of the prices do not shock you than your on your way to build you coach with what ever options you want to add.
The base price from Newmar I would not think will change to much unless if Newmar has year end sale like a car dealership. Maybe long wait.
If you get a dealer to start below, listed price from Newmar, than also the option price list lower, than you will be getting some where, option prices may change through the model year but not so much the base price from Newmar.
