Lake Mead, January 30, 2018 at 8 a.m. Motor home had drive belt broken and front AC compressor seized up. Called Good Sam for a tow to Las Vegas. GS sent All About Auto Service... coming from Bullhead City (90 miles away). His ETA was 11:38. Bruce Gorman and helper arrived at 12:30 without the compressor. He said if sent home now we owed him $600. GS paid to get there, return trip was 1 hours @ $175, didnt even owe $300. He gave extended warranty a guestimate ($1600-$1700). Said he would have a firm estimate+parts in morning. 10:15 am, no Bruce. We called. Said he was in Searchlight, 45 minutes out. Had not called warranty people. Did not have written estimate. Would upon arrival while helper started repair. We stated no warranty approval, no tear down. Showed at noon with firm estimate of $2348.40. Campground had no electricity, Bruce no generator.
