My 30 years experience with RV is that quality of average RV was always poor.
Average RV are build with "cheap, cheap, cheap" but that doesn't make them different from stick-build houses.
Each mid-priced RV I did own had unfinished holes - where exterior wind would flow freely inside, unsecured wires in lot of invisible places and $10 faucets. Add 0 roll-over ratings.
That is why after years, having family safety in mind I bought very vintage Prevost and kept it 11 years, still making new owners of 44 years old coach happy.
Custom Prevost conversion come with gold-plated faucets and insulation where single electric heater would keep 40' coach cozy.
