Moving from Class A to Class B

We have a 2010 Winnebago ERA which is built on the 2500 chassis. We love this vehicle and traveled 3 weeks out west without taking advantage of hotel rooms. We usually get around 20 MPG. The driving is wonderful and we are quite happy with the amount of storage space. I'm not sure whether the 2500 vs 3500 contributes to the gentle rocking as you walk through the van but suspect that it does. There is a motorized sofa but there is room underneath for our large underbed storage box and extra folding chairs. The bed itself is not comfortable despite the ease of setup. We noticed that the new ERA still has the same odd contouring on the seat back which translates to dips when used as a mattress. We got a memory foam topper (king sized and with some strategically folded blankets underneath) works quite well. We did have a macerator issue which we could not trace to any misuse. We added a strainer to the sink and shower to avoid any hair issues. We find the toilet and shower just roomy enough for each of us and never use campground facilities. We replaced the lighting with LED bulbs. Our TV bracket (plastic) has broken and we're thinking that this will require a new TV but will tackle the issue in the spring. Good luck with your search!
