Since I am new to the Forum and learning about RV's I wonder how others feel about New RV versus Used RV. Diesel RV versus Gas RV. What are your thoughts and ideas on this. Is there a significant difference in maintenance costs and repairs between gas and diesel? Are 2 or 3 year old gently used RV's a good option? I ask because I always liked having new as I know how they have been treated/maintained since Day 1. Thanks for any input you may have.
