The screen door strut location on your threshold is most likely not going to interfere with the install of the Lippert SolidStep part # LC791575 but worst case scenario you could relocate the strut to the top of your door to avoid any interference. view full answer...
I would love to help but we do not have any information on your 2005 Dutchmen Denali Fifth Wheel Trailer therefore, in order to determine compatibility of the SolidStep Manual Fold-Down Steps you will need to take two measurements. The first measurement is going to be the width of your door frame (inside to inside). The second measurement is going to be the height from the ground to the bottom of the door (top to bottom).
If the above width is between 28" - 30" and the above height... view full answer...
When trying to replace steps you want to measure the width of the cut out where the steps store. If you measured that width and got 29.25" then that is much wider than normal.
I recommend the SolidStep Manual Fold-Down Steps for 26" to 29-7/8" RV Door Frames part # LC791572 which fits door widths 26" - 29-7/8" and entry heights of 27" - 36". If you measure from the bottom of the doorway to the ground it needs to be between 27" - 36" for these steps to work. These steps will not attach... view full answer...
The difference between the SolidStep Manual Fold-Down Steps # LC791573 and # LC791572 is that # LC791572 is narrower and will fit into a doorway width range of 25- 28-7/8", while # LC791573 will fit doorway widths ranging from 29" - 36".
Both of these steps have a rise/drop of 8", will work with an entry height range of 27" - 36", and can support up to 400-lbs. view full answer...
The correct set of SolidStep Manual Fold-Down Steps for your 2015 Dutchmen Denali Lite 246RK is part # LC678041. I know you said you had a 27-1/4" doorway but the above will work just fine for this as the bracket it mounts is not 28" wide. view full answer...
At one point the Flexco Steps part # SMFP-2100 that you referenced were listed as having the same width you need of 26-1/8 inches between the mounting brackets. We now know that the dimension is really 27-5/8 inches. Since we don't have a step that matches directly you'll either need to move your current brackets or have new ones installed with the Outriggers part # LC301704. The steps of this kit have an 8 inch rise whitch is pretty standard and would be a great option. view full answer...
Since your RV doorway measures 27 inches in width the correct SolidStep kit to get is the part # LC791574 as it fits a doorway width of 26 to 29-7/8 inches.
This kit also is designed for doorway threshold heights of 35 to 44 inches from the ground. view full answer...
