Initially when we were looking for our current RV roughly 4 years ago, the search occurred after three plus decades of RVing in TTs, 5ers, and toyhaulers, we did not consider motorized RVs since we still had a stout truck to pull with. Many of the TTs and 5ers had stackable washer and dryers although they were not a priority for us. After a year or so it appeared my DW was losing interest in our quest for an RV for extended stays and couples living as our kids are grown and out on their own.
We still had our 36' toyhauler although we don't bring along the toys much since kids don't come often, we were not in any rush to buy. At RV shows, once in a blue moon we would walk through some class A rigs never considering them as a future purchase. Limited headroom and maintenance/upkeep of another powertrain were primary factors in avoiding them. For us 5ers provided the best interior space but my DW was growing tired of going up steps to access bathroom & bedroom.
We both are enamored with the RV lifestyle and wanted to continue enjoying our RV excursions, now with trips suited for our adult oriented interests. As we continued to look for a rig for our next phase of RVing, we went to an RV storage yard to look at another 5er but owner could not make it due to an emergency. While there at the storage lot we saw a man with a class A preparing for his next trip, in reality he was getting ready to sell his coach and asked if we wanted to take a look.
Well, we did look at his class A diesel although we did not purchase. What I did notice was my DW was all of a sudden heavily interested in getting our next RV, and that lead to researching all things class A. My advice is take your time and drive/view as many coaches as you can. We had to go to neighboring states to widen our prospects, we went open minded and looked at both diesel and gas class A rigs. Over 2 dozen rigs and 18 months later we acquired our 40' triple slide class A coach.
As with any class of RV, floorplan is a major deciding factor. With motorized RVs another major consideration is powertrain and chassis. Like everything in life, there are pros and cons to every powertrain and chassis regardless of cost. Go in open minded, do as much research as possible, the blanket statements made on RV forums are simply farcical at times, and certainly not 100% accurate. We did our due diligence when looking for our coach, 3 years and 25K miles later it has been a blast and issue free.
