Just pay one of the conversion companies for their design.

Buy a book on building LQ.  One is available in the advertizing space at the top of this forum. It only $25 or so. Read that and get some ideas.

Stop by your local cabinet shop.  Most cabinet shops have CAD software to design kitchens. Most will do the design work as part of your purchase of their cabinets. Once the cabinets are designed, that would be the bulk of your design.

And you could visit lots of trailers for sale and look at what they have in their LQ. I don't suggest you take up a bunch of dealers/individuals time by having them show their trailer when you have no intention of buying. But you can attend the various Horse Expo's, Congress, Road to the Horse etc where manufactures bring in their trailers and put them on open display. Pay the admission fee to the show and walk through the displays and take pictures, make notes and go home and draw up your plan. Many trailer manufactures have floor plans on their websites. Review those and see which you like.

If your husband has the skills to build it, surely he can sketch out a plan once you have your ideas of what you want.

From this website, I'm sure you wil get comments about I liked this or hated that about our trailer and you can use that advice in designing your own. And maybe somebody here would even offer their services for a fee to draw you a design. But any design would only be a concept as you would have to actualy be looking at the physical trailer to see where the supports are built in, exacty where the windows & doors are located, where the radius or tapers of the trailer start and end. Where existing lights may be and will need to be moved or saved. What structural members can I cut and remove if they are in the way and which ones I should never cut. There are just too many variables for somebody a 1000 miles away to draw you a detailed plan.

Some people have used cardboard boxes to create their interiors. Measure, cut, fold, tape them together.

One thing I always scratch my head over, are when cabinets are put in the nose. At the "head" of the bed area. And then when the mattress is put in, with the blankets and pillows and stuff - there is no way to open the doors.  Never figured that one out.

MIne has nose cabinets and I'm glad to have them.  I have a clothing rod to hold shirts, jackets, etc and several plastic containers that hold riding pants, shorts, socks, etc 

In the morning, I pull out the clothes I need and prop the pillows back up. The mattress is lower than the cabinet door and I only have to move a few pillows. It comes in very handy since I use the other cabinets for towels, food, kitchen supplies, etc

When my husband did mine, he also asked what I wanted, and figured the weight to distribute it on each side, so one side wouldnt be heavier than other

you have good space for the nose cabinets in a full nose.  You lose quite a bit of space using a tapered nose

That kind of set up makes sense.

When I was with a GF, she had cabinets on the side walls and in the nose, and we constantly had to pull bedding out of the way - including squishing her foam mattress, to open the doors. Another friend's trailer only barely has clearance under the side cabinets for her mattress. It's super tight once she puts bedding on the mattress.  She bought her trailer with the mattress, but before the interior was done.  I guess when she sent it out for the interior, she didn't send the mattress because it would be in the way.

Looking at factory installations will give you ideas on how much equipment will fit into a given space. You will see similar galley configurations, that maximize utilization of several appliances, within a compact area. Most LQ conversion companies use the same appliances and accessories, so how well they are "packaged" will determine how many will fit into a given space.

As far as the utilization of the front cabinets and the doors interfering with the mattress, that problem is easily solved, whether you are custom building your own cabinets or purchasing premade fronts. If you are custom making your own cabinets, you only have to make the bottom rail a few inches higher than the combination of your mattress and bedding. Then the door bottoms will be clear and not be blocked by the bedding. The inside of the cabinet will be open to the goose floor, and your storage will not be lost.

If you are purchasing premade fronts, again measure the distance from a few inches above the mattress and bedding and the ceiling. Purchase the fronts to those specs. Add a bottom plate to your construction like a toe kick, and again you will eliminate the interference issue with the mattress. The front of the LQ offers a great deal of storage capability, regardless of the trailer's front profile. It's a shame many LQ's do not incorporate this large storage area.
