Hi Ragingbull,

Don, to answer your question; 102 inches, generally.

Vehicle Widths

Summarized here are the California Vehicle Code (CVC) sections related to vehicle width. Some of the CVC sections on this web page are paraphrased for brevity. For the full legal wording, please go to the on-line CVC Width Sections 35100-35111.

35100.1. (a) The metric equivalent of 102 inches is 2.6 meters.

(b) The width measurement of any vehicle with side walls shall be made from the outside wall of the two opposite sides of the vehicle.

CITIES & COUNTIES

35100. (c) A city or county may prohibit a width in excess of 96 inches upon highways under its jurisdiction.

35105. Any city organized under a freeholders' charter may permit a width in excess of these limits when used within the city.

35100. (b) Safety devices shall not be included in the calculation of width. (For more information on safety devices, see "SAFETY DEVICES" below.)

35103. (a) A recreational vehicle may exceed the maximum width if the excess width is from an appurtenance that does not exceed six inches beyond either sidewall. (b) An appurtenance is an integral part of a vehicle and includes awnings, grab handles, lighting equipment, cameras, and vents. An appurtenance may not be used as a load carrying device.

35109. Lights, mirrors, or devices which are required may extend beyond the permissible width no more than 10 inches on each side.

SAFETY DEVICES: According to The California Highway Patrol's Commercial Enforcement Manual "HPM" 82.6 Chapter 8, Revised March 2001, "Size and Weight, Section 1(b)(5):

(a) The maximum permitted width for the items listed in this section is 108 inches, however, they shall not exceed three inches beyond either side of the vehicle.

(c) The exemption granted in this section applies only to the listed items and does not include stake pockets, stakes, and other items of equipment.

Hi Ragingbull,

I'm already 100 inches wide. Adding more width might put me over the legal limit. (anyone know what that is btw?)

I wanted to add panels to both sides.

I've also considered adding fold down panels to the rear of class C, but they would get dirty rather quickly I fear, and hosing them down in below zero weather would be a chore.

Another definitely workable idea is panels that would nest underneath each other. The upper level would be active while traveling and the lower level could be deployed when stopped.

I'm surprised no one has come up with a hinge mount that allows the panels to hang over the side and lock down while moving. When setup at camp you could swing them up and have them lock into place. No roof space taken at all and a little extra shade to boot.

You could probably rig some kind of setup to work in conjunction with your slide outs if you have them.

:h hmm sounds like an interesting idea...

DJ i would price out panels per watt and go with the 60 watt if it is the better deal..if your only looking for an extra day or two may not need a bigger set up..plus with your pop top wieght figures in.. i would go with bigger myself..

I'm running 260 watts, installed it myself (simple to do), and my camper hasn't been plugged into shore power in over a year, we don't conserve much at all. The biggest piece of advice I can give is have the proper size wire providing the least amount of power loss and enough wattage to make up for cloudy days.

totally agree!...why have to park in full sun with roof mounted panels?...plus with portable panel you can angle it to the early morning and late evening sun. Now if you like parking in the sun then thats a different story!

But I'm afraid that when I got back from fishing it would be GONE!!!!! :E

Another advantage to roof-mounted panels - three-stage charging while you're driving. But if you're gonna park in the shade - forget about it. I usually camp in the desert in winter or in cooler locations in summer (coast, higher elevations), so don't mind parking in sun at all.

DJ,

I started out with 190W(2X95W) panels to power everything which includes the biggest draw, my fridge/freezer. 4.7 amps when cycling. I noticed that when the day/night temps went over 90/65F, the fridge was sucking the batteries(4AGM,400amp/hr)even in the day sun. Installed another 140W panel and haven't looked back. Have plenty of power for my wifes hairdryer, some micro use, toaster, coffee grinder, blender, jacks, roof, electronics, late night led's.

My advise is to double what you think you might use. That is both solar and batteries.2 years and genny hour time can be counted on one hand.

I have a small compressor fridge that pulls about 2.5 amps. On a hot day it can run almost full time during the day and maybe 2/3rd at night. Top consumption is probably about 48 AH/day. My wife also uses a CPAP that pulls about 25 AH/day. My lighting is all LED but I do have a 12 v charger for my laptop. Anyway, all together I probably use about twice the power that you plan to use. I have two type 31 HT AGM batteries for a total of 300 AH. I have 270 watts of solar. I would not want to have anything less. On sunny, summer days I have no problem keeping my batteries charged, but that changes in the winter months when the sun is low. It also changes on cloudy days and whenever I camp in the shade. As long as you are going through the expenses of installation and wiring and a controller don't skimp on the size of the panel. Also don't skimp on the gauge of the wiring. Use at least 8, or preferrably 6 gauge, wiring.
