Absolutely take your time and drive as many coaches as you can, this way you can determine which type of drivetrain will suit your needs best. As stated above, there are plenty of motorized RVs available on the current market, rushing to a decision, particularly with class A rigs, can turn into tens of thousands of dollars of repairs and huge losses in resale value. When buying an older motorhome there are so many details to research, sure floorplan is important, but overall condition and proper maintenance is critical to say the least.
We just went through this process and looked at everything in our state, in the end we had to travel 1K miles to purchase our current rig. This was last summer while covid was raging through our great country, tried to line up inspections, unfortunately no RV inspectors were willing to take the job. Luckily owners let us stay 3 days in the RV and I was able to drive rig and verify operation of all major systems. We found the best deals were from private owners, we made sure to have money in place as RVs were selling days after being posted.
