One problem that plagues most Rialta owners concerns the side door and its related electrical locking mechanism.  Many owners have found that if they leave a key in the side door and then allow it to fully swing open, the key head puts a nice round dimple into the sidewall of the vehicle.  Its a shame that Winnebago couldn't relocate the rubber door bumper to this area but I suppose then there would be problems with the key being broken off in the key lock cylinder.

Keep a close watch on the coiled spring that extends from the side jamb where the door hinges are located.  Make sure this never gets kinked or obstructed as the door opens and closes.  Otherwise, the electrical wire inside the coiled spring will get pinched or short out, rendering your electrical lock useless.

Windy areas have a tendency to catch the door and swing it full open (leaving the key dimples in the side).  I know of two easy methods that securely hold the door in the wide open position so that it doesn't slam around when the wind blows:

The mechanical holder is similar to what other larger Class C and Class A vehicles use.  It can be nothing more than a simple hook that holds the door in the open position similar to the old fashioned screen door hook and eye or it can be one of the new modern positive engagement latches as shown on the top of this page.  They generally sell for around $5 or less.

Regardless of what type of hold-open catch you choose to install, almost all will involve attaching the catch to the side body with screws drilled into the wall.  Just make absolutely sure of where the catch is to be mounted because nobody has yet designed a hole mover.

Here is one such sample purchased directly from the Winnebago Parts Store but commonly available at most RV dealers.  It can be attached to the side of the vehicle approximately half-way up the door and the lip of the catch will flip over the edge of the door and hold it open.

The bungee cord involves a little more trial and error in determining the correct length of cord and where to fasten it.  The best combination seems to be a short cord that hooks the door at the bottom and is stretched and attached to the underside of the coach body.  Strong winds may still catch the door and attempt to move it but the bungee cord should bounce it right back into the hold open position.  The disadvantage of this method is that you have to physically bend over and get on your hands and knees to un-hook the bungee cord.  The advantage is that it involves no permanent holes drilled into the coach body.
