The post I used as a guide the most was Bucklands post (last link on the first post to this thread.  In post #52 of that thread Buckland posted a pdf with the steps to follow and they worked for me.  The only thing I screwed up was in drilling one of the holes I hit the lighting wiring and one of my exterior lights no longer works, so be extra careful about drilling out the back - I thought I was but alas....


He installed the top ball for the struts first and the found the location of the bottom.


Anyway, the pertinent text from Bucklands text for your questions may be:

Step ten: lower the roof. I made a jig from a ¼” thick piece of wood 1” wide and 42” long to layout the lower strut locations. drill a ⅛” hole about ½” from one end and then measure, on center, 40” and make a mark. Drill 7/16” hole. It should be 40” center to center. Hang this on the upper ball bracket and let it hang down then move it towards the center of camper. We are looking to put this mark 2 ½” up from the bottom edge of the front overhang. Do this to both sides and really take the time to be sure you are spot on! Then make a divot where you are to drill.


It looks like the document might be at this link:

I’m in the process of installing 3 x 165 watt solar panels on the roof and have been researching installing the 4 exterior gas struts on my 2009 Hawk. It currently has the two interior struts that I want to delete. The panels are 25# each plus I have the two Yakima cross bars installed in the factory ‘T’ track. I’m thinking 60# struts. My thinking is this. If the stock setup is 4 x 30# struts, going to 4 x 60# struts should give me 120 more pounds of force. I have probably close to 100# extra weight up there now. What do you all think?

I also noticed that some folks use the ball brackets top and bottom, where 4WC seems to use brackets on the top and thru bolts (ball stud and barrel nut with large washers) on the bottom. It seems to me the latter option would be stronger? But maybe I’m overthinking this.

We have a 2008 FWC Hawk with one solar panel, and just replaced our ten year old 40# lifters.

Either one of us can easily lift it.  When we put the rocket box on top, it's just barely doable.  If one person pushes up on the outside it helps, or with two inside we can do it.   60# sounds about right.


Be sure you have a strategy to compress the lifters.  I modified a pipe clamp to get mine on.

I have a Grandby, so the roof is a bit bigger, and I have two 200 watt panels that installed weigh about 53 lbs on the Yakima tracks. I changed my struts to 40lb and it’s about right. After I release the end boards, I have to pull the roof down 1/3 to get it started in front and about 1/2 way down in the back. Even so, the initial few inches of lift in the front are tough for my wife.

You can’t really solve that initial lift difficulty with struts because the angle of the struts at that point doesn’t allow them to assist. Best thing is to keep the weight down.

My owners manual contains a red printed warning not to use struts with more than 40 lbs rating. I think the weakest point is the roof bracket for the struts, as you said. There have been people discussing having broken the screws for those in past threads.

Howdy from Jackson Hole!


The modified crankup speaker stand inside lift (discussed elsewhere) works just fine for me starting to get things up. 


The market is flooded with cheapo gas springs. I recommend sourcing from Canadian Gemini Gas Springs. They custom manufacture up to 100 lbs.


Our Jackson Hole Four Wheel Camper dealer told me he doesn't recommend over 60 lb springs because the ball attachments just aren't very strong... He did say he didn't think I'd have problems with my empty Yakima round bars, 1 solar panel, & recovery boards.


Happy Trails!
