Bear in mind that you will have a wider clear opening with the 3-0 door, but two feet less of day light opening. You might also want to consider a 5-0 patio style swinging door, (It is hinged in the center and one panel is fixed and the other swings open and folds against it). They are also called atrium doors (little a) and Verandah doors. It will give you just a few inches more clear opening width than a slider, but offers two panels of glass. These come as inswings only, and generally have a sliding screen that slides from the stationary panel to the operating panel to close.

"Replaced wheels in slider for $175.00." This is the usual problem when a sliding patio door doesn't move smoothly. Each door rides on two sets of wheels set into the bottom of the door. Water splashing up from the patio or lawn during rainstorms works its way into these units and corrodes them. The wheels seize up and the door sticks. As I've learned from experience, if you don't fix this and keep forcing the door, the track may be damaged. So you want to take care of it promptly. Replacement is a pretty easy DIY job. The wheels are adjustable to align the door. You'll find plastic adjustment plugs on the inside of the door at the bottom. Pry them out carefully. Into each hole thus revealed insert a large screwdriver (usually Philips head, but a flat blade may work too). Turn the adjustment screws until the rollers are fully retracted and the door is resting on its track. You should then be able to lift the door and swing the bottom out to clear the bottom track and remove it. Careful, it's heavy! Set the door on its side so you can easily get to its bottom edge. Remove the roller units and take them to a door-and-window shop for matching with replacements. Last time I replaced mine, the cost was around $15 per unit, IIRC. After installing the new rollers, put the door back on the track. Then use your screwdriver to adjust the wheels until the door stands just proud of the track and meets its jamb squarely. It helps to have someone lift on the door to relieve the weight as you adjust. When the doors are square and slide smoothly, put the plugs back in. Done. In my experience, these rollers need to be replaced every 10 years or so. Your "mileage" may vary.

I was not aware that ThermaTru made sliding patio doors? But I would pretty much say I would never buy a Jeldwen exterior door or window.
