Hello Elizabeth, thanks for reaching out. For the 147" wide slide out on your 2023 Forest River Alpha Wolf 26RL-L I recommend the following:
- Solera RV Slide-Out Awning - 151" Wide - White # LCV000163299
This will fit slide outs between 146" and 151" wide. The rail itself is 151" long so this will provide complete coverage for your slide out - and then some. Please just measure and make sure there is at least 7" of free space on either slide of the slide out for the mounting brackets.
A lot of these slide toppers are not custom fitted by year, make and model. We just go off the width of each slide out.
