We have a 2019 Bighorn 3760 EL. We need to remove the bed platform and mattress in order to be able to access a broken slide cable. Has anyone had experience removing the bed and If so can you provide any tips? The RV repair shop is estimating a 4 hour repair to remove the bed, fix the cable and replace the bed. That estimate seems very high. We know we can do the cable repair. How hard is it to remove the bed? Thank you in advance for any tips.
