I'd like to hear what everyone is doing when the need arises to modify their existing battery tray. I'm adding a second group 31 battery but the exiting angle iron on the hitch is not wide enough to accomidate the second battery. The problem I have is the A frame hitch of the TT is not wide enough for 2 of them.

So, I know that I have to make something I'm just not sure which way to go. Should a person extend the angle iron past the trailer's hitch on either side and sit the batteries end to end or create something that can house the batteries side by side? Other advice on weither to weld the new tray or use U hooks would be appreciated.

Every situation is a little different but I made a metal base to just fit into the existing battery tray. On top of this base, I made a new two battery tray which was turned 90 degrees and this gave me enough room for the two batteries.

The original battery set cross ways to the trailer length and the new tray has the batteries parallel to the trailer length which gave me enough room in the A frame.

Good luck, Jim

Like Jim said each situation is different. With my Rockwood I had the added complication with the molded cover for the propane bottles also covering the batteries. I couldn't go wider because of that. My solution was to drop the existing tray about 3" below the frame and mount battery one there and then build a hinged battery tray about 3" above the frame and mount battery 2 there. A Perko switch is mounted next to battery 2. Battery two has to be removed and the hinged tray flipped up to remove battery one. With the molded cover in place it looks stock.

Sounds like regardless of the route I take, welding is the better option here? I'll have to pre-fab everything then find a shop to weld it up for me.

Thanks for the input guys

This has been the biggest pain in the butt of anything on my trailer. No matter how I worked it, I could only get one Group 31 on the stock angle iron (which sits level with the bottom the the frame behind the propane tanks. I built a 2x8 treated lumber shelf, painted to match the trailer for the battery to sit on (U bolted to the frame). Because of the WD hitch hookups, I could not move the battery shelf forward so it is a tight fit. I have been trying to decide whether or not to mount both batteries on the shelf, or bring one out and hook it up each time. Wihs I had a Monster House team to help me! I do have a battery disconnect (Perko). Since the front of the trailer angles out towards the battery, I was prohibited from building up. Not a solution, just commiserating! Thankfully, I have an old trailer and am not entering a beauty contest!!!

Good luck

That's the problem I have. I was hoping I could simply build up but the front of the trailer does angle out towards the propane tanks killing that as an option. Coupled with the tight squeeze of the propane tank cover and the distribution brackets, it has been tough to come up with a solution I'm happy with.

On my trailer two batteries fit just fine end to end. The two pieces of angle iron run from one side frame member to the other and then it has two cross braces that run between them to hold everything in place.

[IMG]http://i2.tinypic.com/t4trev.jpg[/IMG] There are campgrounds that we want to visit that do not have electric sites. So I put in 2 batteries, but they would not fit into the normal rack between the frame. I built a new frame to mount on top of the trailer frame. Used scrap aluminum I-beams, u-bolts, some extra wire, and added an off-on switch. Hard to see in the photo, but the new frame is built with two long side to side pieces, and three front to back pieces[one between the batteries] so that the battery boxes are held on all four sides and can't move.

I did the same as LoveTwoCamp, using steel angle iron, welded to the frame. Took about 5 minutes to cut and weld.

And now for something really different .....

Our TT has a small A frame with limited battery tray space in length, width and height (coach overhangs the A frame). Not enough room for 2 group 31s no matter how I positioned them. I even looked at hanging them on the sides of the A frame like saddle bags but that interferred with the hitch WD mountings.

To solve this problem, I got 2 Lifeline AGM batteries (no ventilation requirements) and put them under the bed. There was plenty of room and I added a wooden fixture (no welding) to hold them secure. Then, since I still had the A frame space available, I put another one of the same kind up there for a total of 3 and 315 amp hours. Works well for us.
