Unfortunately, I have no way of knowing exactly which jack is installed on your 2017 Starcraft AR-One Max travel trailer. We do have a few different replacement switches which I have listed below. You can compare these to the switch on your jack to determine the correct replacement.
Single Momentary Reversing Switch # 37213865
Replacement Extend/Retract Switch # LC49MD
Replacement Power Switch # EJ-3520-PSW view full answer...
Yes. The Fastway e2 Weight Distribution w/ 2-Point Sway Control - Trunnion - 8,000 lbs GTW, 800 lbs TW # FA92-00-0800 will work well for your 500-lbs tongue weight trailer. The e2 uses a hitch ball with a 1-1/4" shank, so for a 2-5/16" hitch ball you'll want to use the # 63840; you may also need a 1-7/8" thin walled socket to install the hitch ball as well, which is available with the # EQ70-00-4800.
This setup will work well with your Starcraft AR-One Maxx trailer. view full answer...
The BTU rating for your Coleman Mach AC 48254C969 is 15,000 so you wouldn't want a lower rated model like the Furrion Chill HE Replacement RV Air Conditioner # FR76PR. You would instead need a 15,000btu model that also comes with a 9-pin adapter to connect to your Coleman system's controller like the Furrion Chill HE Replacement RV Air Conditioner for Coleman Setup - 15,000 Btu - Black # FR32PV or # FR42PV for white. view full answer...
I have a complete replacement option for you, but there are no replacement round spring bars for your Curt round bar weight distribution hitch that are rated for the 500lb tongue weight of your trailer. Since your current spring bars are rated for up to 1,200lbs of tongue weight you will have a very very stiff ride so I do not recommend using them.
To get a system that is rated for your tongue weight range I recommend looking at the Fastway e2 Weight Distribution w/ 2-Point Sway Control... view full answer...
The Replacement Clear Lens for Omega LED RV Porch Light # 328-89-319 is approximately 4-1/2" x 4-3/4" and is the direct replacement for the lens of the Omega LED RV Porch Light with Switch - 357 Lumens - Surface Mount - Clear Lens # 328-007-30SCPE.
I do recommend ensuring you have this exact porch light model as opposed to using dimensions in order to confirm the fit. I have added some links below to video reviews for you to check out as well if you'd like to take a look. view full answer...
You'll have to measure the outside dimensions of the base of your 22 inch Blackstone but the most likely to fit MORryde Generator tray would be the part # MR89RR you mentioned which has inner dimensions of 17-1/2" long x 20-3/4" wide x 2-1/2" tall. view full answer...
I've attached the photos of the instructions that come with the Trailer Valet XL Mounting Bracket # TVXLMB. It's a 2 page document, but hopefully it gives you a good idea of how it mounts and works with a Trailer Valet # TVXL2 or # TVXL25. view full answer...
