Slide out seal replacement cost?

[HTX]

I received a quote from the the RV Service company I have been using for the past 4-5 years to replace all of the seals on all 3 slides for $1600.00 all up including taxes. A little over a grand for the seals the balance for tech time sealants etc. Is that a reasonable price?

Gulp! I do know the seal material was expensive from the Dealer.
