Try calling a couple of local RV dealers to see who they use to replace windshields. Most contract it out to local windshield repair places. I assume you have insurance that covers all but your deductible. My windshield replacement was $3,100. The windshield itself was $1,800 plus $500 shipping. Took about a week to get it shipped.
Your insurance company probably uses a go-between to set things up.
