Yes, just install a new over-sized door.
Look at the
Challengerdoor.com website. They are an OEM supplier to RV manufacturers. Their website has an order form for each of the different door types. You can order any size and they have lots of options.
This might actually have a silver lining to it. Many storage compartment doors could be much larger and would make getting larger items like BBQs in and out much easier. If you can enlarge the opening without issues, I'd go for a bigger door.
For 2014, KZ enlarged the pass-through door in our Spree model and now we can put the BBQ in sideways whereas before they had to go in end to end. Big improvement.
