I recommend using the Solera 18V Power RV Awning Conversion Kit # LC434730 to convert the awning on your 2005 Fleetwood Jamboree GT 31W to electric. The Solera Manual Pull Style to Power Awning Conversion Kit # LC329250 that you found will only work on manual Solera awnings and Jamboree's came with a Dometic A&E awning.
The Solera 18V Power RV Awning Conversion Kit # LC434730 uses a rechargeable battery pack so you will not have to run wiring though your camper to power the awning. This... view full answer...
