Frequently Asked Questions About Renting a Towable RV Near Lanark, IL

If I want to rent a towable RV, how do I tell if my vehicle can handle the tow?

Before renting a towable RV, it is essential to ensure that your vehicle can handle the weight and hitch type of the trailer. You can find this information in your vehicle's owner's manual. You will also need to check the Gross Vehicle Weight Rating (GVWR) of the trailer, which can usually be found on a sticker located on the trailer. It is recommended that you do not exceed 80% of your vehicle's maximum tow rating and make sure you have the proper hitch, brake controller, and sway control device.

Are there any limitations on the types of roads or terrain I can navigate with a towable RV rental in Lanark, IL?

Yes, there are limitations on the types of roads and terrain that you can navigate with a towable RV rental. It is important to check the RVshare rental agreement to see what types of roads and terrain are permitted. In general, most towable RVs are suitable for paved roads and well-maintained campgrounds. However, some rentals may be equipped with off-road tires, making them suitable for moderate off-road terrain.

Are there any additional insurance considerations or requirements when towing a rental RV, and how can I ensure I am adequately covered?

When renting a towable RV, there are three insurance options in case of an accident or damage. RVshare offers different types of insurance coverage, including liability, collision, and comprehensive. It is recommended that you choose the coverage that best suits your needs.

Do I use a sway control device when towing a RV, and does RVshare provide it, or do I need to bring my own?

A sway control device is highly recommended when towing a RV, especially on highways or in windy conditions. Discuss with the RV owner if this is something you will need. RVshare does not provide sway control devices, but the individual owner might.

What kind of braking system do I need for a towable RV rental, and how do I ensure it is properly installed and functional?

All towable RV rentals require a functioning braking system. There are two types of braking systems: electric and surge. Electric brake systems require a brake controller to be installed in the towing vehicle, while surge braking systems are built into the trailer's hitch. It is important to ensure that the braking system is properly installed and functional before towing. RVshare recommends having a professional mechanic inspect the brakes before renting.

Are any unique features or amenities available in towable RV rentals that may not be found in other RVs in Lanark, IL?

The features and amenities available in towable RV rentals vary depending on the unit and the owner's preferences. Some common features found in towable RVs include full kitchens, bathrooms, and sleeping areas. Unique features may include outdoor kitchens, fireplaces, and spacious living areas. It is recommended that you browse RVshare's inventory to find a rental unit that meets your specific needs.

How do I properly load and distribute weight within a towable RV rental to ensure safe and stable towing?

Proper weight distribution is crucial when towing a RV. It is recommended that you load heavier items towards the front of the trailer and distribute weight evenly from side to side. You should also avoid overloading the trailer and keep the weight under the GVWR. It is recommended that you use a weight distribution hitch, which can help balance the weight and provide more stability when towing.

What are the fuel efficiency considerations when towing a rental RV, and how can I minimize the impact on my fuel costs?

Towing a rental RV can have a significant impact on your vehicle's fuel efficiency. It is recommended that you use a towing vehicle with a fuel-efficient engine and avoid driving at high speeds. Additionally, removing any unnecessary weight from your vehicle and trailer can help maximize fuel efficiency. It is also recommended that you maintain a consistent speed and avoid sudden stops and starts.

What kind of maintenance or upkeep do I need on a towable RV rental during my rental period, and what kind of supplies or tools do I need to have on hand for this?

During your rental period you are not responsible for maintenance. Treat the RV with care and maintain cleanliness during your trip.
