I recently did the same on my 2008 Fleetwood 38S. The factory service manual from Denso showed me 3.8# to refill. Don't forget to add oil...I found that information on Freightliner Service Manuals. My total was 14.5oz of PAG46. The Denso manuals and Freightliner manuals are both online. FL manual was through DTNA Connect. Be careful NOT TO FLUSH your condenser. Passages are too small. I replaced mine with one from UAC for about $60. At least bypass it for flush...although when I removed the lower fitting...it stripped the threads and a new fitting had to be obtained.
My compressor fittings had to be cut off...it was a pain to re-crimp etc.
