Finances

My husband and I live in a newer travel trailer. We were living at my mothers house, he bought a new truck, then had to move out so our only resort was a camper... We’ve been in it for 2 years living on husbands grandmothers land. He finally sold the truck that we couldn’t afford the monthly payments on. But now with our son being 3, he needs more room that he deserves. It’s esp hard on me living in such a small space. We have 3 years left on it until we pay it off. Should we try selling the camper to get a house? My husband thinks we should pay camper off and live in it remainder of years but it’s becoming so stressful on me... We can’t afford a mortgage and camper payment 😕

Maybe someone can give us some advice or even an opinion
