Bought 2011 outback 298re . Not much storage under neath . Where is best place buy a roll out type drawer to go in my front outside storage ? Also was thinking of putting a aluminum storage box on rear bumper for folding camp chairs
If you have a ladder on your RV and its just a couple of lawn chairs then maybe a small roof rack would be better. Just be sure to be careful not to create any leaks and seal it up good and tight when you install it. If you put one bar left and right side of the roof it will give you enough to strap them down.
As Gizmo said, bumpers are notoriously poorly supported. A couple lawn chairs should not be a problem, but a box tends to accumulate more things. Make sure it can support more weight than you intend to carry.
