New Truck Too Tall to Tow

**rbolam** · 10-22-2022, 06:38 PM

Our 2021 Ram 2500 had the same issue. Stock tires and stock height, meaning none lifted. We have a Curt A16 puck system and set in the middle height position. I then lifted the exact trailer you have using 3" lift blocks and longer axle U-bolts. I placed the lift blocks between the spring mount plate and the springs. Doing this will not effect or add any extra strain to the stock spring hangers that are welded on the trailer frame. We now are level with in 1/2" and have 6-1/2" of bed rail clearance. We have towed it nearly 2000miles since the upgrade with our new truck and everything is fine, no unusual tire wear, no added sway and the trailer tow's straight down the rode.

I would lift the trailer and keep the truck as stock as possible.
I wish i knew about trailerblocks.com, it would have saved me some time doing my own.

My question is, why do you think you need an F350 dually, to tow a Reflection 150 series? Isn’t that just a little over kill? We towed our Reflection 200MK with our Chevrolet Silverado 3500HD diesel with absolutely no problem, and only because we’d used it to tow our Rushmore Washington before that.
As this is a brand new vehicle, I am assuming you use it for more than just towing your Reflection.

With my old truck, the 5th wheel already tows a bit nose high, so it looks like mods will have to be done before towing with the new truck.

The new truck has 2" blocks under the leaf springs so what are my options to lower the suspension a bit?

Also, I may need to raise the 5th wheel a bit since the hitch itself is already in the lowest position. I was thinking taller tires before raising the suspension on the trailer.

Thoughts?

Has anybody here raised their 150 Series 5th wheel a good 3"?

Thanks for the info, this will be an option once I get the hitch installed to really see the issue.

No dually here...lol

Have you actually hooked up yet and checked. My 2022 F350 long bed 4x4 squats more than my old 04.

Second question - what size wheel came on your F350? If they are 20" you can go to 18" and have the spedo recalibrated On some models the 18" were the stock size.

On my Reflection 220RK I upgraded to 16" tires - that swap got me roughly 1.5" of lift

I am not a fan of lift blocks on the trailer, but they do work.

Hope this helps

Not hooked up yet, just got the bed lined and waiting for the hitch parts to come in. That would be great if the new truck squats more than my y2k F250 with 22 year old springs. But I do have air bags for leveling.
18" wheels on the truck.
Larger wheels and tires on the trailer is one option, but yeah, let me get it hooked up first to see the results.
Thanks for the input!

Hope it works out.

BTW you can also get higher arch springs to get lift. I think that would be a better solution than lift blocks if needed. Springs only run about $100 each

Also have the same blocks under the springs. No idea why your truck sits higher than mine.

@Castlerock
What does your door sticker show for payload?
Mine is 4342 lbs.
Also, what is your GVRW?
Those things might explain the height difference...
