2-Stage Veritical Regulator for Replacement on 2003 Coleman Popup Camper Trailer  

The Marshall 290 model regulator is a standard vertical 2-stage regulator, unlike the horizontal Marshall 260 and Camco #CAM59333 that you mentioned. This means to replace your Marshal 290 you will want the Camco Vertical 2-Stage Regulator #CAM59313…

Hey Jason, so we know that your 2020 Grand Design Solitude 390RK does have 8k axles so in terms of capacity the leaf spring part #e89FV that you referenced would work but we don't have a way to verify the length of your current springs so you…

You can use leaf springs that are rated higher than the axle without any issues as long as they measure the correct measurement for your trailer. For example the 6-leaf double eye spring for 7,000 lb axles part #e64SR measures 24-7/8" eye to…

Hello Brian; the 3/8" difference isn't enough to matter so you can use the #e89FV as a replacement. We do have the U-Bolt Kit for Mounting 5,200-lb to 7,000-lb Round Trailer Axles #APUBR-8 for 3" diameter axles. This has 7" long…

For a replacement leaf spring you need to know your axle capacity as well as the length of your current leaf springs. You will need to measure from center of one eye to center of other eye on your leaf spring that isn't broken. Since these are…

The Universal Group 6-Leaf Double-Eye Spring #e64SR referenced in your question is designed for 7,000 pound axles like what you have on your trailer. Most likely this will work great as a replacement, however I cannot be sure that it is a direct…

In order to replace your Carrier Air V RV Air Conditioner I highly recommend using the Advent Air Replacement RV Air Conditioner for Carrier Setup part #ACCAR135 for 13,500 Btu's or part #ACCAR150 for 15,000 Btu's. This unit will be the only…

Absolutely, the Dexter leaf spring part 072-098-00 is a double eye spring, designed for 7,000 lb axles, with a 25-1/4" eye to eye measurement. The closest leaf spring we have to that is the Double-Eye Spring part #SP-198275 which is a double eye…

Yes, going from a 4 leaf to a 6 leaf spring would add slightly to your ride height. For example, if the current 4 leaf spring has 3/8" thick leaves, and you go to a 6 leaf spring with 3/8" thick leaves, you would be adding 3/4" of…

I checked directly with Dexter, and from what I saw they have a measurement - taken from center of spring eye to center of spring eye - of 24.8", which is the same as our 24-7/8" measurement for the 7-Leaf Double-Eye Spring for 8,000-lb…
