I've posted some of these mods befor, but I thought I would post them all in one place. They are all in our 2012 Fun Finder 210WBS.
This photo shows a magazine rack I made from shop scraps. Also note the wall cabinet to the right. A bamboo placemat cut to size and taped inside the glass hides the clutter inside.
Close up of magazine rack
Adding a shelf and handy pull-out bins greatly increased storage capacity and improved organization
Retracted slide covers this cabinet. Small items may fall during travel and wedge between cabinet and slide causing damage when slide is extended so I constructed a trambour door to close the cabinet:
With trambour door closed items cannot fall and wedge between cabinet and retracted slide. This mod was actually less complicated than it might seem. The door is made from strips of stock screen molding glued to a piece of fabric.
Added custom shelves to store dishes etc (38 pcs) in a very small space (11"h x 13"w x 11"d): 8 plates (sm, lg), 12 bowles (sm, med. lg), 4 mugs, 12 glasses (sm, med, lg) 1 measuring cup, and a small bin for spices. Note tension rods shown in place for travel.
Mag lite hangs in a caddy right by the door - always handy
Torsion box design is light weight but very flat. Rubber feet fit into stove grill to secure it. Note narrow tray behind stove holds kitchen timer/spices.
Flat items store against the wall inside a base cabinet and gate with a spring hinge holds them in place
Another view of the spring gate
Full extension drawer. Note spring gate on the right.
Another full extension pots and pans drawer. By nesting various pots and pans a lot of stuff fits in this small but easily accessible drawer.
Door heater in refrigerator prevents condensation but uses a LOT of power. Added a switch to turn it off and battery life went from 3 days to 7 days!
Added shelves to double storage in bathroom closet. Note extension rods in place for travel
Opened every door and put a bumper wherever its hardware bumped into another cabinet or wall
This shelf may be small but it makes a big difference in convenience
Made this from shop scraps. Bar is made from PVC pipe.
Added shelf
Got the idea for wheel chocks from someone else's post. Also note large concrete pavers. I inset four into the sod in a level plane. Now when I park the camper it is always level.
