chocking question

I use the x-chocks on my Surveyor 186 Sport with an Equalizer hitch. I am wondering if it puts undue stress on the suspension when I have the wheels locked down with the chocks and then have to raise the front of the trailer a foot or more to get the hitch bars on. I figure something has to give, and I'm not sure I understand the physics of it. The Surveyor Sport does not have the same suspension as the torsion system on some of the other models, if that makes a difference. Any ideas, or am I just worrying about something that's not really a problem? Thanks.

I have a "home built" set of checks doing the same thing. I have never worried about stress, but have noticed that if I put them in before the trailer is level, and I adjust anything, they will either get tighter or loosen up. Therefore I put them on last thing, and remove them first thing, before raising corner jacks or changing tongue height. That way I don't worry about about any stress. I always have my trailer chocked to the ground also, and just use the "X" chocks as a simple last thing to do to help eliminate rocking. Good luck. If you do leave them on, I would hope the tires are the weak part, and would give before you bent any suspension components.

Not a problem at all.

Whether it's springs or torsion suspension it's not going to put enough stress on any component to do any damage. Imagine the stresses put on it when you wrench the RV around sideways parking it or getting it into or out of a gas station. You'll bend the X-chocks before you do any real damage to the suspension.

I also use X chocks on my TT. I follow a personal rule to never have them on when I am hitched to the TV. I have no idea if raising or lowering the TT causes any "stress" on anything, but I know it would be bad to try to move the TT down the road with the chocks still attached! I am faithful in doing walk-arounds to make sure everything is ready for travel, but I just don't want to make that big mistake.

I use the X chocks on our Sierra 356RL 5er.
Have always followed the rule of thumb, as soon as the unit is level side to side the chocks go on. They are also the last step before pulling out.

I want them in place while hitching & unhitching.
With our last TT if I forgot to chock the trailer first it could lurch while raising it off the ball.
With a 5er thereís a lot more at stake than just a bent license plate.

On my last post I should have said that ground chocks go on first thing and are the last thing to come off. The X chocks are used for stability inside the TT and are never on when I am hitched.

I use a set of wedge chocks during the unhitching and leveling process then I put the X-Chocks in and leave them in place while parked. The X-Chocks are removed prior to hookup as well and the last thing removed are the wedge chocks. I read this on the internet somewhere but can't remember where.

I'm thinking this procedure on hooking up and unhooking with only the ground chocks in place might allow the trailer to move a fraction of an inch, which is sometimes all it takes to go easily onto the ball and come off easier. Have you found this to be the case? With the x-chocks, I sometimes have to get back in the truck and pull forward or back to get the trailer to drop onto the ball or come off easily.

I had been using X chocks only until our last trip. After backing into our spot I had to use 2 lego blocks under each left tire to level side to side. Then I put in the X chocks. Then I raised the tongue and removed the Equalizer bars. I had to raise the tongue more to clear the ball. When the hitch cleared the ball the TT started turning side ways and slid off the lego blocks. No one was hurt and no damage. I checked the X chocks and they were still tight. The wife said the wheels on the lego blocks did not turn when they slid off the blocks. I will not use lego blocks under wheels again and as other have posted I will use ground chocks along with the X chocks.

I think I will add the ground chocks, too. I wonder if you would have gotten better results if you had removed the equalizer bars before leveling it with the blocks. I REALLY have to jerk on my bars to get them off, and I wonder if that is what moved your camper sideways.

After leveling side to side with boards, I was taught the trailer chocks were the first things on the trailer (before you disconnect completely) and the last things off when you break camp.

I forgot to add I was in very deap pea gravel. This may have contributed to the slipage. It is possible that removing the Equalizer bars before the hitch cleared the ball contributed to this. But I have done this about 40 times with no problems, but having said that it only takes one instance for a set of circumstances to cause a problem. We live, we learn, and we move on.

When told she was pregnant, the coed said, "I don't understand. I've done that hundreds of times this month and I never got pregnant before!"
