Home cabinetry like you find at Lowes are not subjected to weight restrictions like RV's are. Not that they wouldn't work, but a standard S&B base cabinet is probably 2x the weight of one built for an RV. Adding recliners will also probably be much heavier than the dinette you are removing. I know some folks have luck with IKEA type cabinetry as they can be found in lighter woods. Just a caution about doing all this in one concentrated area may cause a weight difference and shift the distribution in your RV.
