I want a fully insulated trailer with double paned windows, washer dryer hook ups, opposing slides
Good luck. LQ horse trailers are designed just for the summer months weekend use and are stored for the winter after the water lines are bled or filled with antifreeze. Hubby and I go to the new RV convention each year, and we have seen only a rare one or two that are insulated to withstand bitter cold. And they are sold that way - it is part of the marketing to get people to buy an RV that is a true winter toy. Standard horse LQs come with no insulation underneath - I’ve seen a fair share that had the water lines freeze in below 32 degree temps at late fall endurance rides. If you want the trailer insulated underneath, you have to do it yourself. Trust me - I asked if mine could be insulated underneath where the water storage and water lines are, and Lakota said they couldn’t do it (for logistic reasons) but I was welcome to do it myself - permanently only after it was out of warranty.
Also was told two slides would compromise the strength of the trailer as needed to haul horses. I have one slide out, and it works fantastic for me.
Truthfully, an LQ isn’t designed for full time living, anymore than the stalls are designed for full time occupancy. I think if you want the true 4-seasons RV, you might as well buy one, and add a hitch to the back to pull a 2 horse trailer.
If Hawk will build a 4-seasons LQ for you, do let me know.
