We went from a $15K 23' trailer to a $25K 32.5' trailer. I wouldn't say quality as far as workmanship are extremely different (both are good) but added amenities (larger frig, gas/electric water heater, recliners, larger entertainment system, larger/electric awning, electric tongue jack, larger slide out, much more spacious living area/bedroom/bathroom, larger holding tanks, etc., etc.) add to weight which means heavier duty frame, axles, large tires, larger brake assemblies, etc. I can clearly see where the extra $10K is between the two trailers.
