Recommended SumoSprings For 2020 Thor Magnitude BH35 Built On 2019 Ford F-550 Chassis

Question

Question:

I would like to know which model of Sumo Springs I should purchase for my 2020 Thor Magnitude BH35 which is on the 2019 Ford F-550 chassis. In looking on your site it appears there are a few weight options and I am unsure which ones are the correct for the weight on this RV.

I would be happy to help!

Since your 2020 Thor Magnitude BH35 built on the 2019 Ford F-550 Chassis has a 19500lb GVWR I recommend the SumoSprings # SSF-111-47 with a 1500lb load rating for the front axle, and the # SS54VR with a 2800lb load rating for the rear axle.

The combination of both these SumoSprings will give you a softer ride along with less sway and body roll giving you a better driving experience.

I included videos of the products mentioned for you to take a look at.

@Skijunkie Glad to help! The correct steering stabilizer would then be the Roadmaster Reflex part # RM55VR.

The wiring on the Electric Trailer Brake Kit #AKEBRK-35-SA are both the same color as they are not positive/negative specific. So you are able to install either wire to the positive terminal and the other to the negative terminal.

A junction box/7-way plug kit like Epicord #277-000141 or #HS381-9000 lets you convert the camper to match the 7-way RV blade type connector format. This avoids the extra connection points and potential trouble spots from using separate adapters.…
