Recommended RV Cover for a 2024 Ram ProMaster with a Rear Spare Tire Carrier  

Updated 10/16/2026 | Published 10/15/2026

Question:

I’ve got a 2024 Ram Promaster 2500 that measures about 19.6 feet in length, plus an external spare tire carrier off the back that adds another 12 inches. Which size cover do you recommend for the best fit?

Hey Stephen.

For your Ram Promaster with the additional spare, I recommend the Adco SFS AquaShed RV Cover for Class B Camper Vans up to 21' Long # 290-12230. This is a Class B RV cover that will work with campers up to 21'. The full dimensions are 21'8" long x 7' wide x 8' tall. I recommend taking some measurements to ensure you have a fit. If you find that your measurements are a tad less, this cover comes with cinch ropes and underbody straps to take up any excess you may have.

Do you travel in your ProMaster year-round, or are you getting it ready for the off-season?

Thanks for the reply, Trent. This will be our first winter season with the camper. We are in the Northeast, and I hope to keep the van in occasional use yearround, for shorter trips weather conditions permitting. Is the product you recommend hardy enough to stand up to a Northeast winter? The cover is for protection from snow and ice while it's parked outside (won't fit in the garage).

@StephenD Well Stephen, in that case it may be worth your time to take a look at the product you originally referenced # CA22DY. This is going to be a tad larger (fitting class B's up to 23') however, it has a much heavier duty build than what I recommended. They will both fit, but with that in mind the super thick roof fabric and reinforced softgaurd foam inserts seem to be worth the extra cost to you. I still recommend verifying the dimensions before choosing (23' long x 85" wide x 118" tall for # CA22DY) I would just ensure you batten down the hatches with the straps on the larger cover.
