Having had 2 RV's with table and chairs sure told us we'd not buy another with table and chairs! All our other RV's had dinettes as will all our future RV's also. Our 54th year of lots of RV'ing so we have lots of experience. The dinette is so much more comfortable hands down. We do not buy cheapie RV's as they cut corners like cushions/foam due to low selling price. We use the storage below the seat as we always have doors on the end for access. We keep many of our canned/bottled food items in a long plastic Tupperware box under one seat.
Store our electrical accessories for laptops, the laptops, flashlights, AAA/AA/C/D batteries, items like soldering iron and solder, ink for the printer, and other various items in smaller Tupperware container boxes all inside a larger Tupperware box under the other seat. The floor under the dinette seats always has carpet so the about 16" wide X 40'long 8" deep Tupperware main boxes slide our so easy for full access to everything stored. Then just slide them back in and close the door. Try that with a table and chair setup!
Beside, the straight hard backs on chairs are so uncomfortable after a few minutes and the seats are hard too. Plus all chairs have to be strapped etc down for traveling but do nothing with a dinette. The nice thick foam seat and back cushion are so much more comfortable even after hours of sitting there. Added is that you can turn sideways when desired on a dinette seat and it's like having a true same height footstool. Keeps your legs up and sis o relaxing!
