Hi BadBob,
I am glad you are asking your "golf club" questions here too. Just to keep it all together for you, here is my input again.
If I recalled correctly, you are interested in a double bed for a couple instead of single beds. If so, I think the brand new "Not Yet Documented" model 2450 (a 2350 plus one foot) will provide you with the golf club storage you seek. As Carol mentioned, you may be able to store your clubs indoors inside in a pantry/closet, or outside in the under-bed storage compartment. If you request the optional longer double bed to benefit easier entry into the bed, it should increase the outdoor storage compartment by one more foot. If you do not get the optional slide-out, you'll get a super-sized outdoor storage compartment along with a wider indoor pantry/closet, both ideal for golf clubs. The outdoor storage compartment will get larger yet because I believe the under-bed furnace is then located on the driver side like we have with our no-slide 2350. Another benefit with the furnace on the driver side is that you gain an extra kitchen galley drawer, otherwise sacrificed for a furnace duct.
More storage or more floor space...it is a notable trade-off regarding a slide-out in a 2350 or 2450.
You would need to confirm all this with the factory. Just give them a call.
