All five Glen-L Travel Trailers in 16' and 20' lengths may be self-contained. Each may be equipped with a complete bathroom including tub or shower and 30 gallon waste holding tank. Water capacity is 30 gallons standard and dual LPG tanks can be installed on the tongue. All models feature an outside trunk and lots of storage space inside including a hanging wardrobe. With the foldout bunk detailed on the plans, 6 adults can sleep on full length beds. You can install all appliances such as refrigerator, range with oven, heater, water heater, and even air conditioning. See photos of Glen-L trailer interiors by clicking here. Tongue weights are correctly matched to the trailer weight and "wide track" axles make for straight and stable towing. The 20' models feature tandem axles. The plans and instructions fully detail the welded frame (no bolts) for easy assembly by you or any local welding shop plus the specifications of the extra capacity chassis gear for a safe, strong unit. The proven Glen-L methods assure that your trailer will be modern for years to come and will look (and be) professional. You'll glow with pride everytime you tell someone, "I built it myself". Best of all, you'll have a truly "custom" unit with those features you add to suit your specific requirements.
