I got my 3 schwintek slide outs replaced with the Vroom system by Tech RV in November. I could not ask for better service and workmanship than provided by Dwayne and Kim at Tech RV.
The dimensions for the slide out components from Keith did not work out. Tech RV ended up using the dimensions I gave them to order the parts from Vroom.
Tech RV installed the 3 Vroom systems, all new seals (including an additional wiper seal across the bottom of each slide) and added aluminum plates at each roller on the bottom of the slide boxes. They also replaced a rotted floor section due to a water leak at the sidewall joint on the passenger side transition section. They accomplished this work in 5 days, as scheduled, and left my coach cleaner than when I brought it to them.
They communicated very well up front (they actually called back when I had questions) and during the repair work. I was welcomed in the shop to watch them work They have a great team and will bend over backward to make you happy.
I obviously was impressed with their service. If you need any rv work done, you should check out these guys. OBTW this isn't a paid endorsement
