Question Towing Question 30 Ft LY w/slide

As I recall, the book recommends a towing limit of 4000 pounds for the Lasnd Yacht with the Workhorse chassis and the 8.1 engine. I am towing a 2010 Toyoto Corolla, which is well under the limit and the performance and gas mileage is good (IMHO).

I was wondering if anyone has had any experience with towing over the published limit by, say 20 to 25%. How does it effect performance in the mountains, fuel mileage, breaking, etc?

As a disclaimer, I am not advocating exceeding the published towing limits. I know there must have been a good reason for establishing this limit. Just trying to determine what the limiting factor(s) may be.

Thanks,

Sam

I am towing a ~2900# BMW with a Demco dolly. I don't have the dolly weight handy I think it is about 600# so I am still under. Even with the Banks upgrade I still notice some differences in power, but corners, etc are a breeze.

I can notice the 25% decrease in weight when I tow my Fit vs. Ranger pu with the 7.4, you having the 8.1 or about 10% more power to haul extra weight for the slide out, I think you would also see a difference. PO put on an extra oil cooler so they must have noticed the weight of the wrangler they towed. The 2000 has 3000# weight limit as it came from AS, alternate would be to put on a Banks system and beef up the tow package. Other half of the equation is braking, it works fine for normal conditions, except for drivers not driving like my normal

I tow a 4500 lb vehicle and get a drop of 1 mpg. Tows beautifully. Haven't been to the rockies with it. just I75 basically. That 8.1 doesn't seem to mind the extra lbs. It will drop from 4th to 3rd occassionaly depending on the grade and length of the grade. As far as I know they used the same powerplant on the 33 ft LY and still had a 4000lbs towing restriction.
The problem will be the hitch receiver and its gross weight capacity. its a class 3/4 I believe but not a heavy duty 3/4. I was just talking yesterday to a towing expert about towing a 7000 lb trailer to a new site and his response was that the hitch receiver would need beefing up. The 8.1? it could handle the job. As far as I can recall the 8.1 has a separate tranny cooler. Braking is not a problem because the toad has its own braking system. Same would apply for a trailer. IMHO

My PO drove down to the Banks factory & had them upgrade the intake & exhaust so I don't know what a stock 8.1 does. I do have dolly braking now, too, but have not tested it on the real steep stuff, and do notice the extra 1K# difference between my old Insight & the BMW 318ti.

Good comments! Keep 'em coming.

When I am in cruse control, my transmission downshifts on most hills. If I think of it, I sometimes take it out of cruse to prevent the downshift. I typically have the cruse control set at the mid to lower 60s (MPH). I try not to get in a hurry anymore; just try to stay out of other vehicles way.

Last Sept. we took a 5200 mi. trip west to Portland, Yellowstone, Salt Lake City and The Salt Flats from home in Northern Wisconsin. We travel in a 2005 30 SL Land Yacht pulling a Jeep Wrangler. I was concerned about the 7 and 8 degree grades both ascending and descending. The 8.1 had no problems, it pulled them in 2nd gear at 3000 rpm at 40 mph. I descended the same way, breaking occasionally to maintain speeds between 40 and 45 mph. Great trip and my worries were for naught.

Rolltop, thanks for the reply. What was your typical MPH on the trip and what was your MPG for the total trip. I find my mileage from tank to tank is not representative of the mileage over a number of fills.

Thanks, Sam

Mine runs best on the open road at about 64 mph, pulling normal hills without much down shifting. I typically get about 8 mpg. On that western trip it dropped to about 7 mpg over all.
