Escape vs Bigfoot towing ?

We have an Escape 19 that we're quite pleased with. However, the ride in the trailer is very rough. This shown by stuff flying around the interior when traveling. I once road about a mile in the trailer to see why stuff was flying. It was a very rough ride. I believe Escape uses a short swing arm with rubber sleeve for suspension and shock. The 19 is a dual axle trailer.

We're thinking of moving to a Bigfoot, 21RB or 25RQ. These, I believe, use a standard leaf spring and separate shocks. Is the Bigfoot less susceptible to giving a rough ride? Do owners have trouble with stuff flying around the trailer? Can anyone compare the Bigfoot ride to an Escape.

Thank you for any help.

What are you running for tires, and at what pressure?
If you fill them to max, your ride will be harsh.

I have run them at full pressure, 50psi. I'll try lowering the pressure and see if it makes a difference. Any suggestions on pressure to run them at?

Good idea, thanks.

It depends on the tire you are running and weight of the trailer.
This is a Maxxis chart.

Escape uses a torsion axle which is the standard used by a lot of RVs.My 19 is not throwing stuff all over the place.


First difference I would notice with the BF is the added width. BF is 8-4 wide. Newest Escape 19 is 7' wide. While the wider width is a nice benefit inside the trailer, its more work towing IMHO.

Glenn:

E-Trailer suggests running at full pressure. If run at low pressure they are likely to over heat due to the heavy sidewalls. Makes no sense to me, lower load will give less deflection and less heating.

We're running ProMeter ST205/75R14. I couldn't find charts for ProMeter, but charts for Goodyear mirror those you have for Maxxis. Likely some standard.

I've been meaning to get a better weight on our trailer. The last I have was 3600lb with axle weight of 3300lb. ETI now says 2860lb dry axle weight. Given that I'd guess my 3300lb is light, we have a lot of stuff on board.

But 3500lb would be some 875lb per tire. The lowest rating on these charts is 1170lb at 25psi. So 25psi? That seems crazy low to me, but it's what the numbers give. What are others running?

Thanks Glenn.

I think the Bigfoot has leaf springs. Can anyone verify or refute this?

What pressures are you running for your '19?

Thanks.

I have Carlisles, the 81 MPH version. Radial Trail HD as I recall. The OEM Carlisles lasted well over 40K miles, so I stuck with them.

The new tires are higher pressure rated, 65PSI max. I am running 50PSI. Driven to AK and back, plus several coast to coast trips. Haven't noticed any problems.

I ran the original Carlisles which were not high speed rated, 45 to 50PSI. Tires are WAY underloaded by Escapes dual axle design.


I can't imagine running 25PSI. Don't do it!!!

Sounds like you have another problem?

Of course, I don't leave stuff loose inside the trailer. Stuff is put away. But I am not having stuff scatter. Now on my 1977 Trillium with its 42 year old axle, you bet, stuff moves around quite a bit.

If I were you, I would head over to the Escape forum. Your experience does not sound normal to me. I'd look for more Escape owners to validate.

My Bigfoot has six leaf springs thought only five but found out when I had a lift kit put in there are six.



I run 42 lbs tire pressure sometimes 45 lbs.

One issue using low tire pressures..... during a side load, skid or, hard left to right sway there is a good chance the tire will break away from the rim.

That would make any bad situation much worse

I run at 50 psi on ours. We have never had things "fly around" inside, and we have not limited the speeds much on gravel roads either.

If I leave my phone on the dinette table it is still there at the next stop, though I would never do that more than once

The chart is not the recommended pressure. It is the absolute lowest pressure that will carry the listed load. And that is the pressure when the tire is cold.

Which means we have to adjust according to what we think is sensible. A hot day on the highway at 25 PSI is asking for trouble. But 25 PSI on a cold day on a rough road at 20 miles per hour would be fine.

This discussion always leads to the question: Who knows more about tires, the manufacturer or the guy towing his trailer? or Who should someone pay attention to with respect to inflation pressures?

Read the chart carefully. It says: TIRE LOAD LIMITS (LBS) AT VARIOUS COLD INFLATION PRESSURES (PSI). To me, load limit means any more load and the tire will be in trouble at that pressure. No safety margin. And that means, its not a good pressure to run. High speed at low pressure causes a lot of heat buildup. Hot weather makes that situation worse.

I have talked to a couple tire shop pros about trailer tire pressure, including my late cousin and current tire shop owner. Both have said that it is best to use the maximum pressure the trailer tire is designed for due to the design of the tire. It's stiff sidewalls which are designed for carrying load that are not meant to flex and will wear much faster if allowed to do so caused from the heat produced by this action. The trailer suspension should take any of the regular road bump and dip abuse, whether torsion axles or springs.

Softer trailer tires also allow more bounce and sway.

I have always kept my trailer tires at maximum pressure for all my trailers which right now is three, a dump trailer, a cargo trailer and my Escape 5.0TA, and have never had any issue due to this.

Anyway, I will always trust the advice of the experts on this.

OK, get more data time. Too little or too much tongue weight can cause trailer bounce.

Take your set up to a local truck stop, get a couple of weights, and for $15 or less you will know what your tongue weight is. Front storage box with battery(s) inside it and lots of gear can drive the weight up. A full fresh water tank, or a bike rack on the back and you drive the weight down.

It could also be a suspension issue on your truck. Bounce is not normal. Sure, on a really bumpy road, you can get some, but on a typical road, not so much. If you google trailer bounce, you will see people getting it with all different brand trailers, so its not brand specific.

If bounce was "normal" on an Escape, you would see people screaming about it on forums like the Escape forum, with a lot of "me too!" comments.

If you are like me, the suspension on my F150 is at or near end of life, 9 years old with 120,000 miles on it, 75% towing.

Bill:

The added width is a concern. The '19 is the same width as the RAM. Another 8" per side would require more concentration when on the road. But I don't think this will effect the ride, other than making it harder to avoid pot holes.

Thanks.
